The Public Media Alliance (PMA) is the largest global association of public service broadcasters. It was first founded in 1945 as the Commonwealth Broadcasting Association. The PMA provides a global context for public service broadcasters as they transit in the digital era. It has members (operating through TV, radio and online) in 54 countries.
The about section of the association's site reads that the PMA works "to identify, research and champion common themes in Public service media (PSM) and provide forums for debate and networking. We also act as a bridge between the academic and public debate around PSM and its changing role. We do this practically through running training, symposiums, exchange programmes, publishing research and reviewing the research of others. We are also working to create appropriate benchmarks for PSM".
