How is the media regulated in the UK and what are the political battles shaping the media system? What are the core principles behind these battles and how should we expect debates around them to develop in the future? The first report of the Uncovering Media Influence in the UK project, published by The Center for Media, Data and Society (CMDS), Goldsmiths Leverhulme Media Research Centre and the Media Reform Coalition (MRC), tries to answer these and many more questions. It addresses three areas of regulation, namely broadcasting, the press and the online media, and analyses the role that state and industry actors have in shaping the policy field.
