"Capitalized on the popularity of Star Trek" might be a better phrase.
SW was/is a great thing on its own, but Trek was HUGE, mid-Seventies.
Huh? Star Trek
wasn't even on the air, aside from reruns in syndication. There was maybe a handful of original novels, and a short-lived cartoon series, but Trek was essentially in limbo during the seventies. Even Roddenberry had moved onto other things: Genesis II, Planet Earth, The Questor Tapes, Spectre, etc.
