Viral marketing is used in Casino Royale to promote products within the film like Sony mobile phones and Heineken beer. These products are also featured on the film's official website to further promote them. Companies pay large sums to have their products involved in major films like James Bond because it exposes global audiences to their brands and can attract new customers. Convergence, such as using flash technology, is also employed on the Casino Royale website to advertise related products and games. This allows film companies to widely promote their content and associated products online.
