This sound is known online as the Warner Bros Pictures intro and is tied to the well-known studio opening used before films and promotional material. It spread through video edits, parody intros and fan-made trailers because the audio instantly tells viewers they are about to watch something cinematic. Creators still use it because even a short snippet adds scale, polish and irony, especially when it introduces something obviously homemade, chaotic or much smaller than a real movie production.
