David Gauntlett is a British media theorist who specializes in studying contemporary media audiences. In his 2007 work "Media Studies 2.0", he argues that the categories of "audiences" and "producers" have become blurred due to websites that allow users to create and share content, like YouTube. This gives audiences more control over their identity and influence. Uses and Gratifications Theory focuses on what audiences do with media rather than what media does to people. It posits that audiences actively seek out specific media to fulfill needs and gratifications, rather than passively receiving media. Media dependency theory extends this by arguing that people become more dependent on media sources that fulfill their important needs and goals.
