Firstly, 20th Century Fox used synergy as one way of promoting the movie. Synergy is the interaction or cooperation of two or more organisations, substances, or other agents to produce a combined effect greater than the sum of their separate effects. There were many companies that 20th Century Fox worked together with in order to increase awareness of the project. One example of this was the collaboration with popular skateboarding shoe company Vans. 20th Century Fox teamed up with top designers for the company and produced a one-off limited edition line of Simpsons-themed Vans. Not only this, but Vans dedicated a whole page of their website to this collaboration, going further than the shoe designs and even recreating all of the sponsored skaters on the site into Simpsons character cartoon form. This whole stunt raised awareness of the movie release, as regular visitors to the website took notice of the collaboration, and buyers of the Simpsons-themed shoes were wearing them in public, creating curiosity amongst people and acting as another source of advertisement for the movie.
Another example of synergy and a similar collaboration was with famous American airway JetBlue. 20th Century Fox redesigned the exterior of one of the running jetliners, painting the entirety in 'Simpsons Yellow', with the Simpsons logo above the wings and paintings of the main four characters along the side of the plane.Initially the plane was opened with costumed Simpsons characters onboard, who were introduced on a yellow carpet. This received a huge amount of publicity and coverage in the media, promoting The Simpsons brand ready for the release of the movie a few months later. Other than this, JetBlue introduced The Simpsons into other areas of the company's operations. For a limited time, JetBlue revamped the website, making much of it Simpsons themed. The most well-recieved of these pages was the 'Destinations' page, where a character was placed next to each of the suggested destinations, giving their opinions on each of them. This brought the characters to life somewhat, making The Simpsons feel like a real part of people's every day lives. It was promotions like this that helped create the large following. Not only did these acts of collaboration benefit 20th Century Fox in the marketing campaign for the movie, but also helped increase sales and brand awareness for the partner company, as The Simpsons' publicity brought attention to them, making the public more aware of the brands.
The next company that 20th Century Fox collaborated with were Burger King. Burger King added an extension onto their website called 'SimpsonizeMe'. This gave users an opportunity to upload an image of theirselves to the site and then see it turned into a computer generated image in the style of a Simpsons character. This promotion was particularly effective as it allowed for involvement and interaction of the audience, which the other synergistic operations didn't so much. This meant that the audience felt more involved in the promotion as they were a real part of it, making them more likely to watch the film upon its release. Of course, the collaboration with the Burger King franchise also increased brand awareness as it meant that Burger King's customers came into contact with The Simpsons' promotions.
Next, 20th Century Fox set out on a whole different set of promotional activities. The idea of these, were to make The Simpsons emerge from a fantasy world into the real world. In order to do this, the distribution company recreated different culturally-popular elements from The Simpsons into real life. The most effective of these was the Kwik-E-Mart, a convenience store set in The Simpsons world, which was recreated to scale in 11 different locations in North America, such as Dallas, LA, Orlando, DC, New York, Vancouver and Las Vegas and acted as a real convenience store that customers could use and buy products (both from The Simpsons, such as Squishee's and Duff beer and from the real world). These stores were strategically placed in these areas, as they are all large cities or states containing a vast population. This way they could target and make as many people aware as possible. On top of this, Kwik-E-Mart gave makeovers to petrol pumps in stations. Once again, this publicity act created the impression that users were a part of the Simpsons world, making them more engrossed in the concept and therefore made them more likely to take part in watching the movie. Another way that The Simpsons movie gained audience engagement was through the use of competitions. The most famous of these was the competition for the winner to host the movie's premiere in their 'Springfield' hometown. This gained a huge following, as to enter the competition, candidates were seeing all of the other promotions around the movie and got equally involved in them all. There were also a number of one-off large scale publicity acts that received an abundance of media coverage and press attention in the run up to the movie release. One of these was the famous chalk-drawing known as 'Homer Erectus' on the side of a large hill in Cerne Abbas, in the UK.
Each of the aforementioned acts worked together in order to create one of the largest marketing campaigns of any Hollywood film. The fact that the people had seen how much money, effort and resources had gone in to the whole procedure, was probably enough to make them go to see the film on their own. Finally, after the long run of these promotions, the typical movie promotion material was released. Such as the trailer and an extensive amount of movie posters. These topped off the whole campaign and gave the potential audiences a real feel for the movie's content, making the marketing campaign one of the most successful in film history.
