I was always partial to WFNX (they played more Pixies), but the biggest rock radio station in Boston was definitely WBCN. Today it was announced that the station would be switching formats from rock radio to sports.

In a major shake-up to the local radio landscape, CBS Radio is pulling the plug on legendary Boston rock station WBCN-FM (104.1) and is switching off the music for the first time in its colorful history in favor of sports.

“The Rock of Boston,” which put disc jockeys such as Charles Laquidara and program director Oedipus on the map, will fall silent next month after more than four decades when CBS Radio moves sister music station WBMX-FM (98.5), or “Mix 98.5,” up the dial to 104.1, CBS announced today.

A new sports station, called “98.5 The Sports Hub,” will debut on 98.5 with the new call letters, WBZ-FM, on Aug. 13. (CBS also owns news station WBZ-AM (1030).
