It took three and a half years to raise the money to make the film, three years to shoot it and a year and a half to do the post-production.
A lot of the footage is downloaded off the Internet from www.archive.org, a website dedicated to free film footage within the public domain.
Sam Gibara, the Chairman of Goodyear, would only agree to be interviewed in the Waldorf Astoria. As the film-makers were very keen to have him on film, they rented a room at the Waldorf. Unfortunately the Waldorf only rents its rooms for the night, so 3 crew members took the opportunity to overnight in one of the world's most famous hotels.
Since The Corporation aired, laws about what can be advertised to children and how much advertisers can push products at children began to emerge in the US and Canada, especially in terms of items considered frivolous, such as toys. Advertisers were under more pressure to be careful about how they worded their advertisements, including avoiding the use of language such as "everybody wants one", "you know you want one" and "all the cool kids have one". However, it is still legal to advertise to children, and many companies have since moved on from television towards advertising online and in YouTube videos since more kids are growing up exposed to the internet and social media.
