94 WYSP. The Rock Station in Philadelphia.
On September 10, 1986, Howard Stern debuted in the 6a-10a slot, simulcast live from 92.3 WXRK radio in New York City.
Many industry observers felt that a morning show produced out of town would not be successful in Philadelphia. However, Stern slowly, steadily and methodically rose past rival WMMR morning host John DeBella to eventually become the city’s top morning personality.
In 1992, Stern beat out all-news stalwart KYW-AM for first place overall in morning drive.
WYSP eventually changed format from Classic Rock, to something called ACTIVE Rock. The station mixed Led Zeppelin and AC/DC with Nirvana and Pearl Jam. It was a very good move.
Philly radio market veteran, Mel Toxic, was then hired to follow up Stern in mid-days. Usually from 11a-2p. So-called zoo-keeper, John Debella, did afternoon drive from 2-6pm.
