There’s two different ways I’d view advertising in films, the first would be how they advertise within the film, for example how magazines and radio adverts look within a movie. The second would be product placement, where companies put their specific product into a film –  “Product placement, also known as embedded marketing, is a marketing technique where references to specific brands or products are incorporated into another work, such as a film or television program, with specific promotional intent.” An example of this would be how Audi promotes their cars in a Spider-Man film.
