The third season of Star Trek was pretty much doomed. Aside from being the year the show was cancelled, it also aired the year before Nelson changed the way they track ratings. If they altered the way they did that prior to season three of Star Trek, then the show would have actually been one of the #1 shows on television. Alas, that combined with gems like Spock’s Brain made sure the series died a premature death.
Now a rare TV promo from 1968 has surfaced. It uses footage from the second season of the show, but it does have Shatner asking everyone to watch Star Trek on Friday nights. Check it out below.
