 At the end of 1974, WPEN was sold to Greater Media, along with co-owned WPEN-FM (now known as WMGK).When the deal closed in January 1975, Greater Media immediately took the stations off the air for some badly needed engineering upgrades.In the spring, WPEN returned to the air as "95PEN" with an oldies format under program director Julian Breen and later, Peter Mokover.
