Star Trek began as an American television series in 1966 and grew into one of the most recognisable science-fiction franchises in the world, with its opening sequence familiar to generations of viewers. Short clips from that opening have circulated online for years as soundboard sounds, reaction cues and edit intros, especially in videos that play on space, exploration or futuristic technology. Its staying power comes from instant recognition: even a few seconds signal science fiction without any explanation, much like the Imperial March does for its own galaxy-spanning saga.
