The fanfare is the signature opening for 20th Century Studios, the film studio formerly known as 20th Century Fox, and has introduced its movies for decades.

Online, creators reuse it as shorthand for cinema itself, dropping it before reveals, parodies and mock trailers to give ordinary footage a blockbuster feel, which keeps the decades-old theme circulating in short-form video.
