Between numerous NPR FM affiliates across the country and the growing number of news/talk outlets on FM (KIRO-FM, KSL-FM, WPGB, KTLK-FM, WTOP-FM, KTAR-FM, etc.) across the country, there hasn't ever been more talk on FM.
What's not seeming to work seems to be FM talk stations with shows from Howard Stern-wannabes (i.e. Lex & Terry, Opie & Anthony, etc.) and most of the other shows of the type that used to populate the CBS "Free FM" stations that have all now died off.
