Star Trek premiered in September 1966 on NBC and ran for three seasons before being cancelled. It was soon placed into local syndication and became incredibly popular. The following was included in the March 10th, 1969 edition of Broadcasting:
Star Trek, coming off NBC-TV at the conclusion of the current season, will be placed in domestic syndication by Paramount Television, producer and distributor of the series. The package will include 70 episodes of the science-fiction series, which will have had a three-year network run.
A total of 79 episodes of Star Trek were broadcast by NBC between 1966 and 1969. I’m not sure why the syndication announcement mentioned only 70 episodes. It’s possible that some were initially held back from syndication but I find that unlikely. Paramount Television placed a full page advertisement in Broadcasting a few weeks later promoting the availability of Star Trek for national syndication. Over the next year, three additional full page advertisements were placed in Broadcasting promoting the success of Star Trek in syndication.
Here are all four of the Broadcasting Star Trek syndication advertisements for your enjoyment. Click on any of the images for a larger version.
It’s likely additional advertisements were taken out during the 1970s as Star Trek continued to enjoy phenomenal success in syndication.
