"However, CBS announced today that it will continue running the 6am to 9am program on close to two dozen of its stations around the country including WBCN 104.1FM in Boston. As of now, CBS lost one national advertiser according to NY Times report. That kind of defensive move by XM wasn't supposed to be required in the satellite radio industry because it operates beyond the rules and regulations of the Federal Communications Commission. Indeed, a good part of the original lure and selling point of XM and its rival, Sirius Satellite Radio, was the way hosts like Opie and Anthony, Howard Stern could finally say whatever they wanted without worrying about fines, suspensions, firings, etc."
