Cross media convergence involves combining different forms of media, such as during production, distribution, or exhibition. Synergy occurs when multiple products from the same company work together to promote each other, providing mutual benefits. For the movie The Inbetweeners, synergy was used by simultaneously releasing the film soundtrack and a yearbook from the movie, encouraging fans to purchase both to experience all the music and content related to the film. Releasing the soundtrack and yearbook together boosted sales of each product.
