                                  INTRODUCTION
The term 'Advertising' originates from the Latin word 'advertere' that means, "to turn the
mind towards". The dictionary meaning of the term advertising is "to give public notice or
to announce publicity". This suggests that advertising acts as a marketing vehicle and is
useful   for   drawing    the   attention   of       people   (prospects)   towards   a   specific
product/service/manufacturer.
DEFINITION OF ADVERTISING
Advertising is defined differently by different authorities and the institutions dealing with
the subject of advertising. Advertising can be defined as "any paid form of non-personal
presentation and promotion of ideas, goods or services by an identified sponsor." This
definition suggests the following features of advertising.
Firstly, advertisement is paid for by the sponsor/advertiser. Naturally, he exercises control
over the advertisement.
Secondly, advertising is non-personal selling. It is a medium of mass communication for
large scale selling.
Thirdly, advertising acts as important marketing tool for presentation and promotion of
ideas, goods and services. Finally, advertising needs the sponsor of the message known.
Advertising will be meaningless if the advertiser is not clearly identified.
FEATURES OF ADVERTISING
2. Paid form of communication: The advertiser has to pay to the media for giving
                                                 2
   publicity to his advertising message. He pays for the advertisement and naturally, he
   decides the size, slogan, etc. given in the advertisement. Advertising is a form of paid
   communication.
                                            3
7. An Art, Science and Profession: It is now universally accepted that advertising
     is an art, science and a profession. It is an art, as it needs creativity for raising its
     effectiveness. Advertising is a science as it has its principles and rules. Advertising is
     now treated as a profession with its professional bodies and code of conduct for
     members. Advertising agencies and space brokers function as professionals in the field
     of advertising.
ADVANTAGES OF ADVERTISING
 The advantages of advertising can be divided into two main groups. One group denotes
benefits to manufactures and other group denotes benefit to consumers. Let us find out
how each of them is benefited by advertising. Benefits of Advertising to Manufacturers:
                                               4
2.   Introduction of new products: Advertising facilitates the introduction of new
     products. Due to advertising, information about new products is given to the prospects.
     This creates demand and the manufacturer is able to sell new products along with the
     existing ones.
5.   Builds brand image: Manufacturers introduce branding for making their products
     popular with distinct personality. The brands are made popular through advertising. As
     a result, consumers develop loyalty towards a specific brand. Advertising builds brand
     image and this develops consumer loyalty towards a specific brand.
                                                5
8.   Sales promotion: A manufacturer can make his sales promotion campaign
     successful by using the support of advertising.
9.   Goodwill builder: A manufacturer can build up goodwill and good image in the
     business world and also among the consumers through advertising. The social welfare
     programmes and community service activities can be given wide publicity through
     advertising. Even the progress of the Organization can be brought to the notice of the
     public through advertising.
The essence of being in business by any business outfits is to produce for sales and profits.
In order to remain in business an organization must generate enough sales from its
products to cover operating costs and post reasonable profits. For many organizations,
sales estimate is the starting point in budgeting or profit. It is so because it must be
determined, in most cases, before production units could be arrived at while production
units will in turn affect material purchases. However, taking decision on sales is the most
difficult tasks facing many business executives. This is because it is difficult to predict,
estimate or determine with accuracy, potential customers’ demands as they are
uncontrollable factors external to an organization. Considering, therefore, the importance
of sales on business survival and the connection between customers and sales, it is
expedient for organizations to engage in programs that can influence consumers’ decision
to purchase its products. This is where advertising and brand management are relevant.
Advertising is a subset of promotion mix which is one of the 4ps in the marketing mix i.e.
product, price, place and promotion. As a promotional strategy, advertising serves as a
major tool in creating product awareness and condition the mind of a potential consumer
to take eventual purchase decision.
                                              6
The Advertising Practitioner Council of Nigeria (APCON) says “advertising is a form of
communication through mass media about product, services or ideas paid for by an
identified sponsor”. Since communication is transfer of idea, attitude, information, mood,
and so on from one person to another through a medium: it may be quite correct to define
advertising as a form of communication. This is because in advertising, persuasive
messages about the products, service or idea are made through a channel. This no doubt is
similar to the communication process of a source sending a message through a channel to
a receiver for a feedback.
In today's fiercely competitive business landscape, where companies vie for consumer
attention amidst a barrage of marketing messages, advertising emerges as a crucial
instrument for organizations to carve out a distinctive identity, drive sales, and enhance
profitability. Advertising serves as the conduit through which brands communicate their
                                              7
Moreover, while advertising can exert a direct impact on sales, its influence on
profitability is subject to additional considerations. For instance, advertising campaigns
that focus solely on driving short-term sales volume may inadvertently erode profit
margins if they lead to unsustainable pricing pressures or excessive promotional
expenditures. Conversely, investments in brand-building initiatives aimed at fostering
long-term customer loyalty and premium pricing may yield more enduring profitability
gains, albeit over a more protracted timeframe.
Furthermore, the advent of digital advertising has ushered in a new era of data-driven
marketing, enabling companies to measure and analyze the impact of their advertising
efforts with unprecedented granularity and precision. By leveraging sophisticated analytics
tools and metrics such as return on ad spend (ROAS), customer lifetime value (CLV), and
attribution modeling, businesses can gain deeper insights into the efficacy of their
advertising campaigns and refine their strategies accordingly.
Against this backdrop, this study aims to conduct a comprehensive analysis of the effect of
advertising on the sales and profitability of companies across diverse industries. By
synthesizing empirical research findings, theoretical frameworks, and practical insights
from industry experts, this research seeks to elucidate the complex dynamics underlying
the relationship between advertising investments and business outcomes. Through a
nuanced examination of the various mechanisms through which advertising influences
consumer behavior, brand equity, and financial performance, this study aspires to offer
valuable guidance for businesses seeking to navigate the intricacies of modern advertising
in pursuit of sustainable growth and competitive advantage
                                               8
According to William J Stanton (1994), advertising consists “all activities that involve
presenting to a group, non- personal, oral or visual sponsored messages regarding a
product, service or idea “Advertising is directed to groups of people and is therefore non-
personal. Companies usually sponsor advertising in order to convince the public that their
products will benefit them. In Nigerian economy, many manufacturers attempt to stimulate
the demand for their products (goods/services). They are not satisfied merely to produce
and trust to the chance that consumers will become aware of their products through the
impersonal interplay of the market.
The role of sales promotion in the form of advertising in promoting product and service
awareness among consumers cannot be overstressed. Advertisement provides a platform
for firms to create awareness about their products or services and how consumers can
make the best out of such products. Olusegun (2006) opined that all advertisement must be
honest and follow ethical standards and must not be perceived by the target consumer as
lie; otherwise it can batter the image of a company and hinder it from building successful
brands. Thus, for advertising to be effective, it must have an appeal, attract attention,
command interest, inspire conviction and must provoke interest (Frank, 2005). In the same
vein, Okeji (2008) posited that a good advert message should not be boring but rather
reflect the lifecycle of the product.
                                             9
He concluded that advertising must be exposed in the right medium as this will enable
organization to reach the right people with the right message. A number of studies such as
Herbert (1982), Nigel (1994), Gladson and Chinedu (2005) and Meshach (2007) have
shown that advertising is a major competitive tool in establishing position in the market
place. Companies use advertising not only to market and promote their products but to
among other things wade-off competitors, improve their brands and create a vintage-point
for their products in the presence of anticipated users, buyers or clientele. Persons,
organizations, groups, government agencies and different sectors of many economies
employ advertising to marshal messages to target 13 public. This is because a well-crafted
advertisement program can be a cost-effective way to disseminate messages and build
brand preferences. As is the trend globally, companies in Nigeria also rely on sales
promotion to get their existing and prospective consumers informed about their products
and services. Among all the tools of sales promotion in Nigeria, advertising has grown
over the years to become the most prominent and easily understandable to firms and the
general public (Haruna, 2005)
It is believed that if a better product is produced, consumers will not necessarily take
special pain of informing themselves of its existence, its worth, its satisfying qualities and
where it can be purchased. Advertising provides information that facilitates the job of the
seller, helps customer make quick decision, informs customer of the presence of a product,
price which it is being sold and placement (where it is available) thereby giving room for
economy of time, energy and money in trying to look for the product. It also announces a
new product, indicates new uses of existing products, reminds customer of an existing
product, about the desirable qualities, stimulates or generates enquires and builds corporate
image to mention a few. The effectiveness of these is expected to result in increased sales
and profit. Profit can be viewed as the excess of total revenue over and above the total
cost. Profit making in any organization is a function of many factors. There is prudence in
vigorously and diligently pursuing organizational goals and objectives. One of such goals
is maximization of the wealth of the owners in an environment where social responsibility
is openly embraced.

The main objective of this study is to examine the effect of advertising on sales and profit
of the company. This research work is designed to achieve the following specific
objectives:
i. To determine the relationship between marketing expenses and profitability of the firm
ii. To determine the relationship between turnover and marketing expenses of the firm.
iii. To determine the relationship between inventory and profitability of the firm.
DECISION-MAKING IN ADVERTISING
                                                11
FIVE M’s OF ADVERTISING
2. Money: This refers to the finance provided for advertising purpose (advertising
   budget). It means the budget allocation made by the company for advertising. Money
   provided is a limiting factor as effectiveness of advertising, media used, coverage of
   advertising, etc. are related to the funds provided for advertising purpose.
   Advertising is costly and companies have to spend cores of rupees for this purpose.
   Advertising should be always within the limits of funds provided. Naturally,
   decisions on advertising package should be adjusted as per the budget allocation for
   advertising. It may be noted that consumer products like toothpaste or chocolate are
   highly competitive with many substitutes easily available in the market. Naturally,
   extensive advertising on TV, newspapers, radio, etc. is required. These media are 16
   costly. Naturally, the manufacturing/ marketing company will have to provide huge
   money for advertising purpose.
   Here, the advertiser has to decide the message to be given, the media to be used for
   communicating the message, the extent of creativity, the specific customer group
   selected for giving the message and so on. The message is also related to the
   decisions taken as regards mission and money provided for advertising. For
   advertising consumer product like chocolate, the message is important. The buyers
   are mainly children and others of lower age groups or for the benefit (pleasure and
   satisfaction) of younger generation. The advertising message should be simple and
   easily understandable with the help of picture or slogan. It should be also attractive
   and agreeable to younger generation. The pictures or slogans used should be short
   and impressive.
4. Media: Media of advertising are already noted previously. The advertiser has to take
   decision about the media to be used for advertising purpose. Media differ as regards
   cost, coverage, effectiveness and so on. The selection of media depends on the
   budget provided, products to be advertised, and features of prospective buyers 17
   and so on. Wrong decision on media may make advertising ineffective and money
   spent will be wasted. This suggests that media should be selected properly and
   decision in this regard is important and critical. For advertising popular and
   extensively used consumer items like chocolate, the media should be selected
   properly. TV advertising particularly a cartoon channel, advertising in children
   books or newspaper supplements for children, advertising on radio programmes for
   children, etc.
                                         13
      making as regards effectiveness of advertising is equally important and essential.
      Such testing facilitates introduction of suitable remedial measures, if required.
The main objective of allocation of huge budget to advertising activity is to increase sales
and profits of the firm. The multivariable forces influencing sales make it almost
impossible to measure with high precision the sales effect of advertising. Consequently to
most advertising research measures the characteristics of an advertisement such as
exposure, the ability of receiver to comprehend, retain and believe in advertisement, it
can be inferred that the advertisement is effective in generating sales. Measuring the
effectiveness, however, is not an easy task, it is still a complex problem and no scientific
method call be applied precisely particularly, in Indian conditions where the advertising
industry is growing because its problems are closely related to the economic and cultural
problems of the country.
(I)      To Get the Cost Benefit of Advertising : The cost of advertising is mounting
         day by day and consequently profits are being squeezed. So, the top management
         should be concerned about the cost benefit of advertising in the various items of
         expenditure in the balance sheet of the company, the contribution of which
         cannot be measured in terms of sales or profitability. Its contribution in terms of
         sales or profitability can only be estimated to reasonable extent. Due to high
         costs of materials and wages, strangulated by higher overheads and taxes, the
         management is reasonable in not approving any expenditure on advertisement,
         which is not likely to bring an additional sale, resulting in additional profits. The
         main concept is that additional cost of advertising must produce additional profit
         and, therefore, the advertising should prove its contribution in total marketing
         efforts like any other allocation of corporate resources or else the advertising
                                            14
        expenditure will be set arbitrarily or be slashed drastically. The cost must be
        linked with the benefits derived. If contribution of any advertising campaign is
        higher, it means the cost benefit is higher and the advertisement is effective.
(III)   To Compare the Results with the objectives and Goals- An objective is a
        broad aim; a goal is specific and quantified objective. Generally, the objectives
        of advertising are warded vaguely in general terms such as to increase sales or
        profits’ or ‘to expand our share of market’, or ‘to maintain a favourable attitude
        of the company and its product. Evaluation of these objectives is not possible. If
        these objectives are stated in terms of the quantity or the amount of sales or
        percentage of total market shares, these are measurable in these terms and
        effectiveness can be measured. If the goal have been achieved the advenising
        may be said to be effective. The result (actual sales) are compared with the goals
        and if the actual performance is better, the advertising is effective otherwise, it is
        ineffective.
(IV)    To compare two markets- Under this procedure, advertising is published in test
        markets and results are contrasted with other market-so called control markets-
        which have had the regular advertising programme. The measurement made to
        determine results might be measurements of change in sales, change in consumer
        attitude, change in dealer display, and depending upon the objectives sought by
                                           15
       the advertiser. Although experimentation is test markets provides an excellent
       means for testing alternative advertising approaches to see if they are effective in
       actual operations, the measurement made are actually measurements of the
       effectiveness of the promotional programme as a whole rather than measurement
       of the effectiveness of the advertising itself.
(V)    To Know the Communication Effect– The effectiveness of the advertising can
       be measured in terms of their communication effects on the target consumers.
       The main purpose of advertising is communicate the general public, existing and
       prospective consumers, various information about the product and the company.
       It desirable to seek post measurements of advertising in order to determine
       whether advertisements have been seen or heard or in other words whether they
       have communicated the theme, message or appeal of the advertising. Clearly, in
       advertisements are not seen or heard or are low in communication ability relative
       to advertisements for comparable products, then the advertising probably is
       ineffective and change is 22 called for. Thus, if advertisements succeed in
       communicating the desired information and developing the favorable attitude, the
       advertising is effective.
(VI)   Basis for planning– Measuring the effectiveness of the advertising is done with
       a view to improve the advertising plan by having a comparative view of the
       objectives set out in the plan and the objectives or goals achieved during the
       course of execution of the plan. If achievement is higher an attempt should be
       made to maintain the position and if there is an unfavorable attitude, this should
       be avoided by making the necessary adjustments in the goals or by improving the
       functioning of the various activities. Thus measuring the effectiveness is
       necessary for the planning. Thus, we can conclude that measurement of
       effectiveness of advertising is necessary otherwise; the whole planning process
       will be disturbed. For this purpose, many tests and surveys are conducted,
       necessary data are collected and are used extensively in the decision making
       process. On the basis of the information collected during the course of surveys,
                                           16
            management confirms the standards and improves them wherever necessary so
            that it may fetch the maximum out of its limited resources.
 The importance of this study is that it will bring to focus the importance of advertising in
 an organization, because of high competitive environment and many brands, the
 importance of advertising in winning customers and achieving brand loyalty cannot be
 overemphasized. The findings of this study will be of importance to business people and
 marketing companies whose product demand is very low because advertising has not been
 included in its market mix.
Advertising has not only become a vital part of our culture and economy, but it has also
grown to tremendous proportions as a business activity and a social phenomenon through
time.
It has had an influence on society as a whole, not just the business sector. Bottoms of the
World Companies use advertising as a powerful marketing communication approach to
achieve their promotional objectives. It's a cold, impersonal style of advertising or promoting
goods, ideas, or services via sponsored media disguised as open sponsorship. When a sponsor
delivers a message termed an advertisement to a large number of potential users or consumers
of a product through one or more mass media, this is referred to as advertising. Advertising is
a critical marketing tactic that uses information and persuasion to promote goods, services,
images, and ideas. Many individuals believe that advertising is a more effective marketing
tactic than personal selling, sales promotion, or publicity.
Advertising, according to the Super Bottoms Marketing Association, is "any paid sort of non-
personal presentation and promotion of ideas, goods, and services by a recognised sponsor by
an identifiable sponsor."
                                                17
forcing beliefs, ideas, and expectations on clients. It is most effective when used to reinforce
consumers' pre-existing positive attitudes, values, and dispositions. Advertising is a highly
visible form of communication that gives a product gravitas while also implies a standardised
offering.
BENEFITS
  The functions of advertisement, and that purpose its ethics, may be discussion below :
1. It leads to cheaper prices. "No advertiser could live in the highly competitive arena of
modern business if his methods of selling were more costly than those of his rivals."
2. It acquaints the public with the features of the goods and advantages which buyers will
enjoy.
3. It increases demand for commodities and this results in increased production.
Advertising :
a) Creates and stimulates demand opens and expands the markets;
b) Creates goodwill which loads to an increase in sales volume;
c) Reduces marketing costs, particularly product selling costs.
d) Satisfied consumer demands by placing in the market what he needs.
4. It reduces distribution expenses in as much as it plays the part of thousands of salesman at
a home. Information on a mass scale relieves the necessity of expenditure on sales promotion
staff, and quicker and wider distribution leads to diminishing of the distribution costs.
5. It ensures the consumers better quality of goods. A good name is the breath of the life to
an advertiser.
6. By paying the way for large scale production and increased industrialization, advertising
contributes its quota to the profit of the companies the prosperity of the shareholder the
uplifts of the wage earners and the solution of he unemployment problem.
7. It raises the standard of living of the general public by impelling it to use to articles of
modern types which may add to his material well being. "Modern advertising has made the
luxuries of yesterday the necessities of today ..................... It is a positive creative force in
                                                  18
business. It makes two blades of grass grow in the business world where one grew before.
8. It establishes the goodwill of the concern for the test articles produced by it and in course
of time they sell like not cakes consumer search for satisfaction of their needs when they
purchase goods what they want from its beauty, superiority, economy, comfort, approval,
popularity, power, safety, convenience, sexual gratification and so on. The manufactures
therefore tries to improve this goodwill and reputation by knowing the buyer behaviour.
To sum up it may be said that advertising aims at committing the producers, educating the
consumer, supplementing the salesman converting the producer and the dealer to eliminate
the competitor, but above all it is a link between the produce and the consumer.
                                              19
be kicked out as and when sufficient capital is available by advertising on a large scale.
Immediate result may not justify the increased expenditure but it will no doubt secure future
sales.
                                               20
OBJECTIVES OF CAMPAIGN
  The advertising campaign, especially those connected with the consumers aims at
achieving these objectives :
i) To announce a new product or improve product.
The institutional advertising campaign on the other hand, have these objectives.
v) To enable company salesman to see top executive consistently when making sales calls,
and
Developing the campaign programmes. The advertising campaigns are prepared by the
advertising agencies, which work an behalf of their clients who manufacture product or
service enterprises, which have services to sell. The word campaign is used because
advertising agencies approach their task with a sum Blanca of military fanfare in which one
frequently hears words like target audience logistics, zero in and tactics and strategy etc.
                                                21
The account executive co-ordinates the work in a campaign. The creation of an advertising
campaign starts with an exploration of consumers habits and psychology in relation to the
product. This requires the services of statistical trained in survey techniques and of others
trained in social psychology. Statisticians select samples for survey which are done by trained
interviewers who visits individuals, included in the sample and ask question to find out about
their taste and habits.
This enquiry often leads to a change in a familiar product. For instance bathing soap may
come in several new colours or cigarette in a new packet or talcum powder in another size.
Such interviews are often quite essential to find out the appeal of advertising message for a
product that would be most effective with consumers.
David Ogilvy describes a consumers survey to find out the most meaningful benefit in which
women are interested when they buy a face cream. The largest preference as given to "Cleans
deep into pores" followed in order of importance by prevent dryness, "is a complete beauty
treatment, recommended by skin doctors" makes skin look younger' contains estrogenic
hormones, pasteurized for purity,
prevent skin form aging, smooth our wrinkles ogilvy concludes, form this voting come one of
Helena Rubinstein's most successful face creams. We christened it deep cleanser, thus,
building the winning form into name of the product.
After getting the data the account executive puts together the essential elements of his clients
brief, interprets the research findings and draws up what he calls the "advertising strategy".

different contexts, immediate action appeal.
3.Creating the Advertising platform :
  An advertising platform consists of the basic issues or selling points that an advertiser
wishes to include in the advertising campaign. A single advertisement in an advertising
campaign may contain one or more issues in the platform. A motorcycle producers
advertising platform should contain issues which are of importance to consumers filling and
such issues also be those which the competitive product do not posses.
4. Determining the Advertising Appropriation:
The advertising appropriation is the total amount of money which marketer allocates. For
advertising for a specific time period. Determining the campaign budget involves estimating
now much it will cost to achieve the campaigns objectives. If the campaign objectives are
profit relating and stated quantitatively, then the amount of the campaign budget is
determined by estimating the proposed campaigns effectiveness in attaining them. If
campaigns object is to build a particular type of company image, then there is little basis for
predicting either the campaigns effectiveness or determining the budget required.

THE PROBLEM'S STATEMENT
The issue that this research project will address is summarised in the following statement.
1. Lack of knowledge of the product's existence on the side of the client.
                                         CHAPTER 2
                                 REVIEW OF LITERATURE
 A well planned and organized advertising scheme has the potential of increasing
 awareness of a business products or brands in the environment in which the business
 operates, ceteris 6paribus. In consequence, the advertised brands or products increase their
 share of the market. This increased share of the market will translate into increased
 turnover, ceteris paribus. Under stable tax regime, profit after tax should increase and
 profit attributable to shareholders should rise correspondingly under well managed
 advertising. Advertising is used primarily to inform potential customer of; (1) the
 availability of products or services, (2) when they are in season, (3) where you are located
 and (4) anything special about your product.
 According to Fill (1999), the purpose of advertising is to supply the means which
 advertising, public relations and sales promotion are communication tools to be accessed
 by marketers. One distinct feature of communication is that the target population or
 audience must understand the information and so it must be as simple as possible. Dunn et
 al. (1978) viewed advertising from its functional perspectives; hence they define it as a
                                                27
 paid, non-personal communication through various media by business firms, non-profit
 organization, and individuals who are in some way identified in the advertising message
 and who hope to inform or persuade members of a particular audience. Morden (1991) is
 of the opinion that advertising is used to establish a basic awareness of the product or
 service in the mind of the potential customer and to build up knowledge about it. Kotler
 (1988) sees advertising as one of the four major tools companies use to direct persuasive
 communications to target buyers and public noting that “it consists of non-personal forms
 of communication conducted through paid media under clear sponsorship”. According to
 him, the purpose of advertising is to enhance potential buyers’ responses to the
 organization and its offering, emphasizing that “it seeks to do this providing information,
 by channeling desire,
 and by supplying reasons for preferring a particular organization’s offer. While writing on
 advertising nature and scope, Etzel et al. (1997) compactly capture all advertising as
 having four features: (i) A verbal and or visual message, (ii) A sponsor who is identified,
 (iii) Delivery through one or more media, (iv) Payment by the sponsor to the media
 carrying the message.
The meaning of advertising cannot be definite as it means different things to different people
depending on their perceptions of what it is. According to Kotler (2000), advertising is any
non-personal presentation and promotion of ideas, goods, or services by an identified
sponsor. Advertiser includes not only business firms but also museums, charitable
organizations and government agencies that direct messages to target public. Advertising can
also be defined as any paid non-personal communication about an organization, products,
services or ideas by an identified sponsor (Bennet, 2006)
 Advertising is any paid message presented through various media, such as television,
 radio, magazine, newspapers or billboards by an identified source. Scholars such as
 Sandage and Rotzoll (2002) have argued that advertising is a costeffective way to
 disseminate messages, for instance to build brand preference for a product or to educate
 people about government policies or to avoid consumption of hard 22 drugs. Companies
 embark upon advertising not only to sell their products, promote their goods, but also to
 create efficient defense to curtail competitors‟ moves. Frank (2005) saw advertising with
                                              28
the aim to persuade people to buy. Modern advertising is a product of the twentieth
century; however, communication has been a part of the selling process ever since the
exchange of goods between people started (Kazimi, 2005). Modern commercial
advertising is the persuasive force that aims at changing customer‟s behaviors. This is
important because consumer wants and needs change as their economic positions improve
and as they pass through different stages. It is therefore desirable for advertisers to assess
the impact of advertisement on their products‟ performance from time to time (Kotler,
2000). Shimp (2007) in corroborating Richards and Curran (2002) defined advertising as a
paid, mediated form of communication from an identifiable source, designed to persuade
the receiver to take some action, now or in the future. A broad variety of rational motives
can be used as the source for advertising appeals such as convenience, economy, health,
sensory benefits, quality, performance, comfort, reliability, durability, efficiency, efficacy
etc; all of these are to stimulate the consumer to patronize a product (Duncan,2002).

3. Advertising like other promotional forms should attract attention among those people
                                              31
they are intended to influence; and
4. Advertising should generally persuade the target audience to place an order i.e. to really
close the sale and perhaps assume it has been done. There must be readily recognizable
link between the promotion and desirability of buying the particular product.
In recent years a number of studies suggest that a firm’s advertising (Frieder and
Subrahmanyam 2005; Grullon, Kanatas, and Weston 2004; Joshi and Hanssens 2007,)
directly affects stock returns. This is in addition to the indirect effect of advertising
through increase in sales revenues and profits.
Srinivasan and Hansens (2007) carry out an extensive literature survey on the impact of
advertisement on market and firm value. The effect of the advertising on consumers rests
on the theory of message repetition. It can be classified into three main effects: a current
effect on behavior, a carryover effect on behaviour and a non behavioral effect on attitude
and memory (Pechmann and Stewart 1988; Sawyer 1981; Sawyer and Ward 1976).
Researchers have tried to estimate the effects of advertising on brand sales using field data
(Leone and Schultz 1980; Vakratsas and Ambler 1996). Most of these studies focus on
many technical issues involved in efficiently capturing the unbiased effects of advertising,
given the limitations of field data (Hanssens, Parsons, and Schultz 1990). Deeper analysis
of these studies finds that the effects of advertising are significantly greater than zero but
do vary by market and product characteristics (Assmus, Farley, and Lehmann 1984;
Sethuraman and Tellis 1991).
 Few studies have addressed the effect of advertising effects on sales. Little has been
researched on capturing the impact of how the effects vary by creative medium or vehicle,
and time of day for broadcast advertising (e.g., Bhattacharya and Lodish 1994). In
particular, no study has researched the effects of advertising by these three factors
                                              32
simultaneously. While marketers know that that consumer behavior is influenced by
multiple factors, yet little research has been done on understanding the impact using the
integrated marketing mix model ( Sethi 1977, Feichtinger, Hartl and Sethi, 1994). This is
attributed to the fragility of advertising’s effects and the complexities involved in getting
bias-free estimates.
Naik and Raman (2003) present an insight as to how a marketer or a shareholder is keen
on measuring the impact of marketing (advertising investment) on market performance. To
assess these effects marketers often use regression analysis. Arguing that OLS models
introduce biasing effects, they put forward the Weiner Kalman Filter(WKF) that provides
estimates that are closer to the true parameters. Advertising's effectiveness lies in its
capability to help stimulate or maintain sales (Eachambadi 1994; Mantrala, Sinha, and
Zoltners 1992; Naik, Mantrala, and Sawyer Sethi 1998; Vidale and Wolfe 1957). Thus,
advertising is frequently used as an independent variable in explaining changes in sales
(Lilien 1994).
Abraham and Lodish (1990) believe that advertising effectiveness has to be captured by
the additional sales of a product over and above those that would have happened in
absence of any advertising or promotion. Although advertising managers have long
believed that advertising's impact on sales can persist longer than the current period
(Clarke 1976), the tendency to assume that advertising's effect on sales is short-term is yet
prevalent. They further argue that the longer uses of advertising are better than less and
shorter uses of it irrespective of the nature of contribution of advertisement to sales (Jones
1992, 1995). The inability of measures to differentiate the impact of advertisement
between its short term and long term effects have resulted in wastage of advertising
expenditure (Abraham and Lodish, 1990; Bass 1969). Eechambadi (1994) uses the analogy
of capital budgeting process to capture the effectiveness of ad spending on sales and
profitability. He suggests that the brand managers be allowed to spend as much as they
want on advertising if the return they generate is able to beat an internally agreed hurdle.
His belief rests on the premise that absolute size of the ad budget does not matter but the
return on that budget is the criteria for ad effectiveness. The basic duopoly model leads to
an equilibrium which can be determined analytically (Dixit, 1979); this basic model does
not demonstrate any dynamic behavior. Introducing advertising into the model allows
                                             33
firms endogenously alter demand which does invoke dynamic behavior but is analytically
intractable.
Graham and Ariza (2003) present a model that optimizes allocation of firm advertising
expenditure using a simulated annealing approach. Sterman et al (2007) use an approach
that combines duopoly theory with the behavioural theory of the firm. Research on the
response to advertising had primarily looked at the shape of the response function (Aaker
and Carman 1982; Simon and Arndt 1980; Mesak 1999), the dynamics of advertising
effects (Simon 1978), and the interaction of advertising with other promotional mix
elements (Winder and Moore 1989; Wildt 1977).
Luo and Donthu (2001) apply DEA – Data Envelopment Analysis – to the question of
how to measure the efficiency of the advertising in the traditional media. Further Yunjae
Cheong (2006) uses the similar model to carry out a study on the evaluation of ad media
spending efficiency. This model focused on how one could measure, maximize and
benchmark the effects of advertising media spending thereby improving the effectiveness
of advertising.
Yew, Keh and Ong ( 2005) report that intensive investment in advertising contributes
positively to the one-year stock market performances of non-manufacturing firms.
However their results were inconclusive whether manufacturing firms benefit from
investment in advertising as measured by the three-year stock market performance.
Mathur and Mathur (1995) using event study methodology concluded that investors
react positively to announcements of advertisement changes leading to higher market
value for the firms.
                                             34
Boddewyn & Leardi, (1989, p. 365), states the following sales promotional types:
reduced prices and free offers, premium offers of all kind, vouchers and samples, the
supply of trading tramples, promotions which are linked with charity, and furthermore
promotions related to prize of different kinds, including some other incentive programmes.
All these are employed by companies to increase the profitability through motivating
consumer’s to make an immediate purchase. Another form of sales promotion is a group
promotion. A group promotion would be to offer two complementary but different
products (for example/- soap and toothpaste) being sold together maybe at a reduced price
for a limited time. Some researches prove that sales promotions do not have a constant or
continued effect on volume of sales of a firm which tend to diminish and come at the
initial level at which it was before the sales promotion is being offered (Dekimpe,
Hanssens and Silva-Risso 1999; Pauwels et al. 2002; Srinivasan et al. 2000). However the
usefulness of sales promotion, that whether it promotes, the long term growth and
profitability among brands for which it is projected is not compulsory. (Kopalle, Mela and
Marsh, 1999).
Research conducted by Ailawadi and Neslin (1998) revealed that sales promotions
motivate the consumers to make immediate purchases and also positively impacts the
consumption volume. A research conducted by Dekimpe et al. on four different product
categories to find out the permanent and temporary effects of sales promotions on sales
volume. Their research has proved that there are rarely any permanent affect of sales
promotions on the volume of sales. Thus showing that sales promotion does not change the
structure of sales over the long run, this implication is analyzed through our research also.
However the long run profitability of sales promotion is largely linked with the cost
parameters and magnitude of response, but we have made brand loyalty the benchmark of
long term impact, because it is consumer’s brand loyalty that ultimately increases the
customer lifetime value, i.e. an important indicator of future profitability. Dekimpe et al.
also revealed in the research that the diminishing impact of sales promotion may also be
                                             35
because of choice of brand, quantity which is purchased and category incidence. This
dimension is also covered in our research through the analysis of extraneous variables. In
another research conducted by Koen Pauwels (2002) he has examined the permanent
impact of sales promotion on accumulative annual sales for the two product categories
which include storable and perishable products. It was found that perishable and storable
product categories lack permanent effects of sales promotion. Furthermore it is revealed
that affects of sales promotion are short lived and persist only on average 2 weeks and at
most eight weeks for both product categories. The research’s results prove the common
concept that sales promotion makes only benefits which are temporary for the established
brands.
Thus it becomes very difficult and unsafe to generalize based on the findings of the study.
Abiodun (2011) examined the impact of advertising on sales volume of Starcomms Plc.
The study used frequency tables, percentages and Chi-square to establish relationship
between advertising and sales volume of the company. Despite the attempt made by the
study to establish relationship between advertising and sales volume of the company, the
study suffers from a number of weaknesses. The study failed to clearly reveal the impact
of advertising on the sales volume of the firm because it utilized primary data that does not
adequately capture the impact of relationships. Similarly, the sampling procedure of the
study and the absence of validity and reliability test for the research instruments may have
affected the data collected and by implication the findings of the study. Lastly, the number
of questionnaire copies filled and returned was not adequate by any systematic standard
                                             36
for the test of hypothesis. In a related study, Akanbi and Adeyeye (2011) examined the
relationship between advertising and sales volume of Nigerian Bottling Company Plc
between 1999 and 2009. Using the OLS regression technique and t-test on annual time
series data of advert costs and sales volume as surrogates; the study found a significant
relationship between advertising and sales volume of the company.
Summarizing the above, they conclude that “advertising then consist of all the activities
involved in presenting to an audience a non-personal, sponsor-identified, paid-for message
about a product or organization”. Those views of Etzel et al., (1997) coincide with the
simple but all-embracing definitions of Davies (1998) and Arens (1996). For instance,
while Davies states that “advertising is any paid form of non-personal media presentation
promoting ideas/concepts, good s or services by an identified sponsor. Arens expressing
almost the same view describes advertising as “the personal communication of
information usually paid for and usually persuasive in nature about products (goods and
services) or ideas by identified sponsors through various media”.
From the preceding, it could be concluded that the purpose of advertising is to create
awareness of the advertised product and provide information that will assist the consumer
to make purchase decision, the relevance of advertising as a promotional strategy,
therefore, depends on its ability to influence consumer not only to purchase but to continue
to repurchase and eventually develop brand loyalty. Consequently, many organizations
expend a huge amount of money on advertising and brand management.
A lot of empirical studies have been carried out on advertising, one of such was carried out
by Karounwi (1998), he said the producer’s ultimate goal is to sell product and make
                                             37
profit and one of the ways which he could achieve this is through advertising. The
researcher noted the fact that there are stiff competitions in the market especially with
advertising messages reaching the ultimate consumers first. Wright (1991) believed in is
tentative findings that consumers are not helpless victims of advertisement once they are
constantly exposed to various kinds of advertisement, they become motivated.
Olawuyi (2004) in his own study, says that men of the world who want the best wherever
they find it know that advertised goods are invariably the best of its kind for reliable
product can stand up to intensive publicity. The manufacturer who makes a public claim
must be able to prove it by advertising goods that are good for buying.
Also, Galbraith (1963) states that advertising has an effect on the rising sales of brand
product categories and therefore increases the profit of the product. In a study undertaken
to find out the role of social status in decision process, Kassarijian et.al. (1995) stated that
increased social interaction permits the more rapid spread of new ideas and that there is a
relationship between advertising appeals and social character. It may be necessary to
mention that marketing activities are interwoven and no one’s activities are in stage and
except one stage is completed the company may not go over to the next stage. This has
resulted in people seeing marketing as an integrated system.
Stanton (1978) in one of his books sees marketing as a total system in which we price,
promote, and distribute satisfying goods and services to potential customers. Arising from
Stanton’s definition, it becomes evident that marketing activities are all geared toward
consumer’s wants, needs, and satisfaction with a view to making some level of profit.
Satisfying the needs of target market brings one to the use of 4p’s in marketing otherwise
known as marketing variable. When discussing the marketing variable many talk about the
types of product, the price attached to the product, the advertising aspect to create product
awareness, persuasion and finally, the place or distribution/logistics. For any good
organization, the satisfaction of the needs of target market is highly dependent on its
fashion and how it manipulates the four utilities to suit the needs of the consumers and the
                                              38
organization.
As a matter of fact, profit making should not be the primary objective of any organization
rather, quality product will satisfy consumer’s needs and enhance repeat purchase.
Definitely the company will make some profit in order to remain in business. This is also
applicable to the beverage industry, it is pertinent to mention that this will only be
achieved when a company produces a quality product and this product is reasonably priced
based on its value to the consumers and a good promotion employed to inform and create
product awareness and the product is within the reach of the target consumers.
According to Young (1965), advertising does not inform the public that a product exists
but promotes its benefits, it also persuades, induces people to like, prefer and buy a
product to others.

 2.2.1 RELATIONSHIP       BETWEEN ADVERTISING, SALES AND PROFIT:
                                              40
A metrics have been developed to assess and measure consumer awareness and loyalty.
Besides many studies use the AIDA or its adaptations that has been around from the early
20th century (Strong 1925). Few research studies concentrate on measuring the sales and
profit effects (Gattigon 1993, Montrala 2002; Naik et al 2007). A cursory glance at this
suggests that these effects have been studied on the US consumers and markets. It
therefore is imperative to study the impact of spending on advertisements on the sales and
profitability of the firm.

Test of Research Hypotheses:
 Having given a careful analysis of the data obtained from the Annual report and accounts
 of Securities and Exchange Commission, PZ Cussons Plc, May & Baker Plc, Nigeria
 Bottling Companies Plc, UAC Plc and Unilever Plc the hypotheses earlier formulated in
 the first chapter of this study will now be tested and the results fully discussed below. In
 all, there are two hypotheses, which are to be tested, and in doing so, SPSS version 17.0,
 specifically regression, is employed, with a value of 0.05 (level of significance) that
 corresponds to a 95% confidence level. Therefore, all tables presented are SPSS analysis
 outputs.
Hypothesis One:

PZ CUSSONS INUDSTRY-                          Y = -178.708+ 2.374x1
The results of the Regression show that at the 5% level of significance, only the
coefficients of the intercept and Turnover/Revenue are statistically significant. The
analysis of the coefficients of multiple determinations (R 2) which measures the goodness
of fit of a model revealed R 2 of about 0.807, 0.602, 0.316, 0.501 and 0.591 respectively
which implies that 80.7%, 60.2%, 31.6%, 50.1% and 59.1% of the systematic variations in
the Profit after Tax are being explained by the variations in Turnover/Revenue.
Also, the Analysis of the T-Statistics (T-TEST) which is expressed as the ratio of
estimated parameter to its standard error was used to test for the individual significance of
individual estimated parameters. The model is statistically significant given the F-value
computed is 8.375, 5.003, 6.550, 6.120 and 2.891 respectively which is greater than 2.82
from the F- table. The Durbin-Watson statistics revealed 1.653, 2.994, 3.159, 3.352 and
1.874 respectively which is approximately the criteria of 2.0 and it can be deduced that
there is an absence of serial correlation between the variables observed for this study.
INTERPRETATION:
Fcal 8.375, 5.003, 6.550, 6.120 and 2.891 respectively > F tab 2.82, we therefore reject H o
and therefore there is a significant relationship between marketing expenses and
profitability of the firm. Alternatively, the level of significance 0.05 is greater than the
asymptotic significance value (P-value) of 0.030, 0.037, 0.008, 0.016 and 0.005
respectively we therefore reject Ho and accept Hi that there is a significant relationship
between marketing expenses and profitability of the firm.

The results of the Regression show that at the 5% level of significance, only the
coefficients of the intercept and Turnover/Revenue and Inventory are statistically
significant. The analysis of the coefficients of multiple determinations (R 2) which
measures the goodness of fit of a model revealed R 2 of about 0.974, 0.821, 0.729, 0.533
and 0.593 respectively which implies that 907.4%, 82.1%, 72.9%, 53.3% and 59.3% of the
systematic variations in the Profit after Tax are being explained by the variations in
Turnover/Revenue and Inventory.
Also, the Analysis of the T-Statistics (T-TEST) which is expressed as the ratio of
estimated parameter to its standard error was used to test for the individual significance of
individual estimated parameters. The model is statistically significant
                                             50
given the F-value computed is 18.949, 2.901, 11.343, 7.077 and 7.728 respectively which
is greater than 2.82 from the F- table. The Durbin-Watson statistics revealed 2.116, 2.944,
2.535, 3.007 and 1.840 respectively which is approximately the criteria of 2.0 and it can be
deduced that there is an absence of serial correlation between the variables observed for
this study.
INTERPRETATION:
Fcal 18.949, 2.901, 11.343, 7.077 and 7.728 respectively > F tab 2.82, we therefore reject Ho
and therefore there is a significant relationship between turnover and marketing expenses
of the firm.
Alternatively, the level of significance 0.05 is greater than the Asymptotic significance
value (P-value) of 0.016, 0.023, 0.021, 0.031 and 0.038 respectively we therefore reject H o
and therefore there is a significant relationship between turnover and marketing expenses
of the firm.

NIGERIA BOTTLING COMPANY-                     Y = 453328.483+ 0.227 x1
The results of the Regression show that at the 5% level of significance, only the
coefficients of the intercept and Inventory are statistically significant. The analysis of the
coefficients of multiple determinations (R 2) which measures the goodness of fit of a model
revealed R2 of about 0.670, 0.672, 0.313, 0.704 and 0.501 respectively which implies that
67.0%, 67.2%, 31.3%, S70.4% and 50.1% of the systematic variations in the Profit after
Tax are being explained by the variations in Inventory.
Also, the Analysis of the T-Statistics (T-TEST) which is expressed as the ratio of
estimated parameter to its standard error was used to test for the individual significance of
individual estimated parameters. The model is statistically significant given the F-value
computed is 4.058, 4.088, 5.910, 4.159 and 4.000 respectively which is greater than 2.82
from the F- table. The Durbin-Watson statistics revealed 2.216, 2.633, 3.312, 2.965 and
2.702 respectively which is approximately the criteria of 2.0 and it can be deduced that
there is an absence of serial correlation between the variables observed for this study.
INTERPRETATION:
Fcal 4.058, 4.088, 5.910, 4.159 and 4.000 respectively > F tab 2.82, we therefore reject H o

                                       CHAPTER 5
Conclusion: The study examined the issue of “examine the effect of advertising on sales
and profit of the company (Nigeria Bottling Company Lagos, UAC Lagos, PZ Lagos, May
& Baker Lagos and Unilever Group Lagos)”. From the data and information collected
scientifically tested and analyzed in the course of the research the following conclusions can
be deduced from the study that there is a significant relationship between marketing
expenses and profitability of the firm. There is a significant relationship between turnover
and marketing expenses of the firm. Also, there is a significant relationship between
inventory and profitability of the firm.
