First, I find the statement from Les Moonves over Imus firing to be totally hypocritical considering CBS has been and still is, by far, the worst offender of trash and potty talk and stunts of all broadcasting companies: Janet Jackson, Howard Stern, Don Imus, Opie & Anthony, All of their Free FM's, etc...
As for the Free FM's, I'd say they have to clean them up but since no one is listening, who is going to complain? This will give CBS good reason to dump most of the Free FM formatted stations without upsetting Wall Street as they raise their new "Higher Ethical Standards" banner.
Both NBC and CBS execs should have been fired over this as well. They allowed it and encouraged it for GREEN for way too long. They're a worse offender than Imus.
