When Did William Shatner’s Star Trek Get Named The Original Series?

From its debut in 1966, Star Trek: The Original Series was just plain Star Trek, until the TOS label was later added to distinguish William Shatner’s show from the wider franchise. 57 years later, it’s incredible that Star Trek has lasted as long as it has, spawning a huge entertainment franchise across multiple media forms. TOS was canceled in 1969, and it wouldn’t be for another decade that the USS Enterprise would take flight once again, in Star Trek: The Motion Picture. The success of those movies revitalized the Star Trek franchise and led to a hugely successful TV revival, spawning three other spinoff series and a new movie franchise.
