There have always been stations with small owners that ignored research, did absurdly large playlists and thought that they could "make hits". With deeper programming support staff, as soon as those stations got bought they generally improved with either local or shared research and better programming practices.
Remember that 1995 was when full consolidation began. The reason that step was approved was that over half of all US radio stations were not profitable... and that was in the pre-Internet and pre-mp3 world. The Docket 80-90 proliferation of new stations made it hard for small and medium market stations to be profitable and all the upgrades and move-ins added many more stations to markets like Austin or Jacksonville or Phoenix; when there is no profit, programming suffers.
