Time For Really Early TV

Here is, I believe, a kinescope of the April 22, 1949 telecast of the Admiral Broadway Revue, which aired simultaneously over the NBC and DuMont networks.  It was a forerunner of the more successful and classic Your Show of Shows which began airing on NBC in 1950.  The show starred Sid Caesar with Mary McCarty, Imogene Coca, and Marge and Gower Champion.  Produced by directed by Max Liebman, who later produced and directed YSOS.

Time For Ole Tyme TV Variety

Here is a kinescope of the April 22, 1949 NBC telecast of the Admiral Broadway Revue, which starred Sid Caesar, with Mary McCarty, Imogene Coca, Marge and Gower Champion, plus Janet Collins, James Starbuck, Kenneth Remo, Sydney Smith, Tom Avera, Ronnie Cunningham, the Arnaut Brothers, and Charles Sanford's orchestra.  The series aired simultaneously on NBC and DuMont (the latter so that the show can be seen in Pittsburgh, where DuMont owned that city's only commercial TV station).  This was the forerunner to the legendary Your Show Of Shows (1950-54, NBC), with Sid, Imogene, Carl Reiner, and Howard Morris.  Max Liebman, who produced and directed Your Show of Shows, produced and directed Admiral Broadway Revue, which the sponsor canceled in the summer of 1949 after 18 shows.
