A “landmark study” released today on commercial radio ownership claims that just 61% of minority station owners have just a single station, “in an industry that until very recently has experienced steadily increasing consolidation.” The study by two Santa Clara University law school professors and David Honig of the Minority Media & Telecommunications Council also lists a number of minority owners who have lost stations for financial reasons. They say the FCC’s records make it difficult to do broad research about minority ownership, but it’s clear that more than half of today’s minority owners got their start prior to the 1996 Telecommunications Act. That’s evidence to them that the Telecom Act spurred consolidation but didn’t help minorities enter the business. The estimated number of minority-owned stations is unchanged between 2007 (based on a Free Press study) and 2009. This year’s total of 815 stations is about 7.24% of the 11,250 commercial stations. Congress is considering restoring the former minority tax certificate law, to encourage owners to sell to small businesspeople and other “eligible entities.”
