While broadcasters seek to either maintain or relax the local radio ownership limits, citing greater competition for audio delivery and the dire economy, public interests groups told the commission just the opposite this week….The Future of Music Coalition says its studies show that radio has suffered from a lack of format diversity since passage of the 1996 Telecom Act; it also argues that counting format names is an inadequate measure for format “diversity” because “just 15 formats make up 76 percent of commercial radio programming.” FMC proposes a “fixing radio” agenda with prevention of further consolidation at the top of the list.
