Answer: The Mike Douglas Show. 

The Mike Douglas Show, a daytime talk show, first premiered on WKYC-TV in Cleveland, Ohio, in 1961. The show moved to Philadelphia's KYW studio in August 1965 and was produced here until the show was moved to Los Angeles, California, in 1978. The show was cancelled in the early 1980s.

In Philadelphia, the show was first produced at the KYW studios at 1619 Walnut Street. It moved to KYW's brand new studios at 5th and Market streets in 1972. Throughout its run in the city, Douglas was joined weekly by various co-hosts, celebrities, and entertainers. And, occasionally, the show was shot on location at various spots in the city.

The Andrew McKay collection of photographs of the Mike Douglas Show (#3315) at HSP contains various press photographs of guest stars and co-hosts of the Mike Douglass Show from 1972 to 1976. HSP's library also contains a number of published items on local television productions, such as American Bandstand: Dick Clark and the Making of a Rock 'n' Roll Empire (call number ML 3477 .J33 1997).
