WBUR/WGBH Revisited

WGBH and WBUR continue to compete for the same market share...the NPR news listener. It was feared when WGBH switched formats to News and information that the move would split the audience. It hasn't quite turned out that way.

Certainly WBUR lost share of the market while WGBH made very modest gains. More importantly, public radio collectively lost share of the Boston Market. Public Radio's Share of the market, (Persons 6+) according to PPM data provided by RRC, has dropped from 9.5% to 7.0% of the radio audience.

I compared the quarterly topline reports from Winter 2010 to Spring 2011.
Without more data, I can only guess at what is happening. It seems public radio is less appealing now to the Boston Market than it was in the Winter of 2010.
