Synergy involves using multiple media platforms together to promote a single product, like a film. Convergence involves different media companies collaborating on a single product. The films Attack the Block and Super 8 both used synergy and convergence in their marketing. Attack the Block used social media, outdoor ads, and TV promotions. Super 8 had a viral marketing campaign, was promoted through other media like video games, and was released by multiple studios. Both approaches helped promote recognition of the films and boost their box office returns.
