The Disney Channel, starting as a 16-hour-a-day cable service, had its premiere in April 1983. Mr. Wagner was president for about a year.
It could be said that Mr. Wagner got his start in television in 1956 when, as a member of a troupe of United States Navy seamen, he did a stand-up comedy bit on “The Ed Sullivan Show.”
(Early in)Mr. Wagner's career (he)was host of a long-running radio show, “Living Opera,” on WNYC.
