Note: I am not referring to live TV bloopers, but to footage shot for (and not used in) a TV program.
Just off the top of my head: Many outtakes exist from Groucho Marx's fab game show "You Bet Your Life". A "gag reel" exists from some Paper Mate commercials with Art Linkletter "Rushes" exist from some Australian news reports of the 1950s
Additionally: "The Ed Wynn Show" was aired live in the west coast, but on the east coast aired several weeks later. After the live broadcast was over, they would sometimes re-do part of the show for editing into the east coast kinescope. In some cases the unedited retakes still exist.
