Encouraged by the way that Google has come to dominate the global market for online search advertising, Clear Channel and its rival CBS Radio are now eyeing the potential to dominate the global market for online radio advertising, and fend off Google. In July 2008, Clear Channel announced its plans to dominate the ‘internet radio’ market, by launching a ‘portal’ offering a vast array of radio programming, along with a new business unit to sell online advertising inventory. Although Clear Channel’s targets initially are US advertisers and US internet users, the company will likely target the UK market when it eventually decides to roll out its business model for online radio to the rest of the world. As a result, within the next decade, the UK commercial radio sector could face an additional source of competition from overseas media companies offering radio content delivered via the internet

This report considers recent activity concerning the radio sector’s Digital Audio Broadcasting (DAB) platform and examines the implications, particularly in view of the recent establishment of a government working group examining the future of digital radio, and given weak consumer acceptance of DAB. It concludes that overcapacity of DAB spectrum is an issue that will only be exacerbated by the planned launch of a further DAB national multiplex by Channel 4 in 2008
