The platform now hosts that have disappeared from mainstream streaming services years ago. One landmark sci-fi film in YouTube's collection gained 25 minutes of previously lost scenes—unavailable anywhere else.

Silent masterpieces like Nosferatu (1922) and Battleship Potemkin (1925), early sound-era horror gems, educational films, zombie features, romantic comedies, and animated cartoons. As new films enter the public domain annually (copyright expires after 95 years in the US), the library grows—so Citizenfour (2014) appears alongside It's a Wonderful Life (1946) and House on Haunted Hill (1959).
