The fanfare comes from Alan Silvestri's score for Back to the Future, the 1985 science-fiction film directed by Robert Zemeckis about Marty McFly travelling in Doc Brown's DeLorean time machine. Its heroic brass theme became shorthand for adventure and success long after the film's release. Online, editors repurposed the cue as a win sound for gaming victories, sports highlights and challenge completions, often alongside applause such as clapping and other victory cues like Here Comes The Money. It endures because the melody is instantly recognisable, even to viewers who have not seen the film.
