You can call it video essays, Let's Plays, news reports, slop videos, and so on.
To repeat fgiesen/ryg: to a content plumber, it's all content, just like the mail system delivers packages and doesn't really care what's in them. The video engineers at YouTube don't care whether it's a news report or a slop video, as long as the frames get on your screen. However the sender and receiver had better care what's in the package or something's gone horribly wrong.
But what do you call their output?
What do you call an illustrator's output? A photographer? What about when all of that shows up on your feed collectively?
Content is a gross word.
