The march was part of a larger nationwide effort to protest the cancellation of the show, but it’s unclear how many people actually participated.
Case and point: the LA Times shared a story of a Caltech protest in 1968, in which students were all up in arms.
Students at Caltech stood outside the NBC building with signs reading “Draft Spock,” and things of that nature in an attempt to keep the network from removing the show from their programming.
While some around the nation were protesting the Vietnam War, the draft, and the establishment in general, these 200 strong students marched to the steps of NBC offices in Burbank to protest the rumored cancellation of Star Trek.
