The Colgate Comedy Hour

'Colgate Comedy Hour' was a first-rate comedy-variety series, performed live from New York City and featuring some of the biggest names in American show business at the time. The series was sponsored by Colgate-Palmolive, a 'health and beauty aids' company which had established a healthy presence in the sponsorship of entertainment since the early days of radio. In the 1940s, Al Jolson had starred in a weekly radio show sponsored by Colgate Tooth Powder, but he mistakenly kept identifying the sponsor as 'Colgate Toothpaste': a different product altogether, which was sponsoring a different radio show at the time.

Apart from its excellent entertainment value, the Colgate Comedy Hour is also important for a technological reason. The episode broadcast live on 22 November, 1953, hosted by Donald O'Connor, was the very first colour tv broadcast. Prior to this, all colour tv transmissions had been closed-circuit only.
