Crain's NewYorkBusiness.com has told me some amazing news. Today, at 5:00 pm EST, the all-talk radio station 92.3 WFNY will change back to its historic rock roots as WXRK, or K-ROCK, according to sources at CBS Radio (NYSE: CBS).

The move couldn't come fast enough.

Its the first sign of change under new CEO Dan Mason, who replaced Joel Hollander last month.

The move back to rock music ends the all-talk format when Howard Stern went to Sirius Satellite Radio (NASDAQ: SIRI) at the end of 2005. WFNY has struggled from day one. The station had a paltry 1.3 share of the audience during the 2007 winter quarter, the same a year ago.

Opie & Anthony, currently serving a 30-day suspension at XM Satellite Radio (NASDAQ: XMSR), will get to keep their morning drive job on the new (old) WXRK. After 9 am, the station will return to its rock roots.

Just minutes ago, Opie from the O&A was the first live voice listeners heard, as Guns N' Roses' "Welcome to the Jungle" played in the background. The station officially kicked off the format change playing one of Nirvana's greatest hits, "All Apologies."

Its O.K. K-Rock, I forgive you.

Joel Hollander is resigning and will be replaced Dan Mason as President and CEO of CBS Corp.'s (NYSE: CBS) radio unit. According to analysts, Holdander's departure could be a signal of a move by the company to sell off some of its radio stations. No official reason has been given for his departure and Bank of America securities analyst Jonathan Jacoby made it clear that he was speculating as far as the sales of the radio stations.

If CBS does pursue the sale of its radio stations it will be interesting to see how much interest there is. With the emergence of satellite radio grabbing headlines, FM radio hasn't been in the news so much of late.
