Studios for the early WFIL radio stations were in the Widener Building in downtown Philadelphia. Under Triangle Publications' ownership the stations were moved to a new broadcast facility at 46th and Market Street in West Philadelphia adjacent to the Arena, the first broadcast facility in the nation specifically designed for television broadcasting. It was in this new broadcast center that Triangle began broadcasting "Bandstand" (later called "American Bandstand"), first with Bob Horn, then with Dick Clark as host. Clark started on WFIL radio as a disc jockey in 1952, arriving from Utica, New York. He continued hosting the TV program for 31 years, the last 30 as a national show carried by the ABC Television Network. Clark moved the program to Hollywood in 1964.
