Problematic dilution of radio content in the U.S.A. After the FCC loosened ownership rules, mega-corporations bought up scads of radio stations and optimized their music for maximum profit -- i.e. made them all sound the same, because if a song works once, by golly it'll work everywhere. Has led to a falloff in radio listenership, precisely because all stations sound the same. As a result, some FM stations have dropped music in favor of talk formats. Sad.
