What is unique about Youtube is that everything is non-fiction. When was the last time any Youtube success was fictionalized content?
That's what Youtube Originals tried to change, and failed at.
YouTube is definitely lacking in the traditional "TV show" department if that's what you mean.
A 40 minute video essay feels insightful, I know that I'm really there for the entertainment but I can justify it to myself like I'm learning something and that makes me feel good. The things that I categorize as "mindless entertainment" are short and low commitment; I don't feel bad watching a 3 minute comedy sketch. When YouTube was trying to push Cobra Kai on me I thought, "that is not how I want to spend the next 30 minutes," then I wasted the next 30 minutes anyways on mindless entertainment with a series of 3-4 minute videos.
Cobra Kai seems successful. Unfortunately, YouTube dropped it and Netflix picked it up. The irony is that, while Google makes a lot of money from ads, its sibling Netflix kinda sucked at advertising the show. I didn't know about Cobra Kai until it was on Netflix.
"What does the Fox say" is non-fiction?
"Baby Shark" is non-fiction?
"Gangnam Style" is non-fiction?
Today. There is ton of it.
