Synergy involves simultaneously releasing related products across different media to promote each other. This has a larger promotional effect than releasing a single product alone. Conglomerate companies like Sony can effectively use synergy by owning various smaller companies and mediums. Cross media convergence combines two or more mediums, such as TV, film, websites, during the production, distribution or exhibition of content, like when Adele's song promoted the film Skyfall across different industries and platforms. Old and new media also converge as magazines produce websites and TV incorporates interactive elements.
