BOSTON (CBS) – WAAF, a longtime rock radio station based in Worcester and Boston, has been sold and will start playing contemporary Christian programming this weekend.

Entercom sold WAAF to the Educational Media Foundation, which runs religious radio networks, for $10.75 million. The programming switch will begin Saturday, under a network affiliation agreement, Entercom said in a statement.

“If you grew up as a fan of rock and roll music here in the Commonwealth, the fact that there’s not going to be an AAF anymore is a big disappointment,” Governor Charlie Baker said, “but it’s just one more lesson in the fact that culture, time, music – it all moves on.”

WAAF will continue to air on its existing HD stations, 104.1 HD2 and 93.7 HD2 and on Radio.com, according to the company.

The Federal Communications Commission has to give final approval for the sale. That’s expected to happen this spring.

WAAF had scheduled a 50th anniversary concert for April 16 at the DCU Center in Worcester. It’s not clear yet if that will still be held.

The station’s long history in Boston included an infamous stunt on April Fool’s Day in 1998 when DJ’s Opie & Anthony were fired for a prank claiming Boston Mayor Tom Menino had died.
