A prosumer is a person who combines the roles of producer and consumer by creating and sharing content online through activities like social media. Developments in technology have given consumers tools to become prosumers by making cameras, microphones and other equipment widely available. Proliferation of hardware and online content refers to their rapid growth in media. This benefits producers by allowing on-demand viewing and mobile access to content, easier online promotion through websites and apps, and viral marketing through YouTube. However, it also makes piracy easier and allows negative opinions to spread quickly. Producers promote and distribute content through converged platforms like apps, games, websites, social media and soundtracks to engage audiences and promote films.
