January 22, 1968 –
The comedy show Rowan and Martin’s Laugh-In, hosted by Dan Rowan and Dick Martin, premiered on NBC television on this date.
One of the trademarks of the series was the fast cutting that happened in between videotaped segments. Blackouts, one-liners and sketches were edited together in such a way that the show had a very rapid, almost frenzied, pace. This was done before computer controlled editing machines were invented, so much of the show was edited by hand.
