Convoy
Premiering in 1965, Convoy was a war show featuring John Gavin as Commander Dan Talbot and his crew aboard a cargo ship that helped supply troops with supplies and rations during WWII. The show had low ratings from the start and was cancelled after just one season.
Holmes & Yo-Yo
Holmes & Yo-Yo attempted to recreate the magic of TV dynamic duos a la Starsky & Hutch and Cagney & Lacey. However, this show didn’t live up to the expectations. Yo-Yo was an android that helped detective Holmes solve crimes. Although it’s not a bad premise, it just didn’t do well and was seen as a huge failure. It was not renewed after its first season.
