The fanfare belongs to the classic studio logo sequence used before 20th Century Fox films, with its famous brass theme composed by Alfred Newman in the 1930s. For decades audiences heard it in dark cinemas while searchlights moved behind the monumental Fox letters, making the sound inseparable from the start of a feature presentation. As clips moved online, editors kept the audio as a shortcut for instant movie glamour. It remains popular for trailers, memes and intros because a single burst tells viewers a big production is supposedly beginning.
