In 2007, Gauntlett published online the article Media Studies 2.0, arguing that we need to recognise the changing media landscape in which the categories of 'audiences' and 'producers' blur together. He argues that there is a shift from a 'sit-back-and-be-told culture' to a 'making-and-doing culture'.
He's really useful as a current theorist you can refer to in your exams.
