Star Trek is one of the highest-grossing media franchises of all time. It has changed our cultural landscape in so many ways since it first aired in 1966. The franchise has generated billions of dollars in revenue, leading to a wide range of spin-off games, novels, toys, and comics. Star Trek is noted for its social science, too, with its progressive civil rights stances and its celebration of future diversity that began with The Original Series, one of television's first multiracial casts.
