And something worse happened, didn't it? They cancelled Star Trek and put on lost in Space or whatever.
Lost in Space started before Star Trek and was canceled a year before Star Trek was.
The boring one, the one with Khan, the one where Spock returns, the one with whales, the dumb one, the last one, the one with Kirk, the one with the Borg, the stupid one, the bad one, the new one, the other one with Khan.
