Very few of them were ever made on video. Actually neither are they films.
What do we call them? I don't know, but they are not videos as they are on Youtube.
From what I can tell, there isn't a definite rule about film versus video, but people tend not to use the term film to refer to things that aren't at a theater or being projected. And the main reason for them being called films at the theater is that there's over a century of history of using actual film both for recording and display and theaters are purely digital these days as it's hard to even get the appropriate films to run through older projectors. In common use, videos are basically any other motion picture.
As for YouTube, I'm guessing it's because of when the site launched and gained popularity. If I understand correctly, people say they're watching Tic Tocs or something of that nature.
