The document discusses the purposes of two main forms of research undertaken by media industries:
1. Market research involves collecting statistical data about audience size/composition for media products, measuring audience awareness of products/services, and understanding audience opinions and behaviors to assess market competitors. 
2. Production research provides information to help media companies find the right target audiences for advertisers. It offers detailed demographic data about audiences to ensure ads are targeted appropriately, such as advertising holidays for older adults to an older audience.
Both forms of research are important for media companies to understand their markets and produce content that attracts the desired audiences.
