The downturn in radio advertising is certainly not limited to just the United States. It has caught up to British commercial radio, as revenues in the United Kingdom fell 10% last year. RadioCentre blames the revenue shortfall on several factors, including the economy, and having stations broadcast in both analog and digital signals, which cost the radio sector approximately $113 million. Overall, 2009 commercial radio revenue in the U.K. fell 10% to $810.2 million, following a 6.4% drop in 2008. In the U.K., analog signals are expected to be phased out by 2015, with all radio stations preparing to broadcast with digital signals by then.
