To follow this up, one of my favorite channels on Youtube is Outdoor Boys. It's just a father who made videos once a week doing outdoor things like camping with his family. He has amassed billions of views on his channel. Literally a one-man operation. He does all the filming, editing himself. No marketing. His channel got so popular that he had to quit to protect his family from fame.

Many large production companies in the 2000s would have been extremely happy with that many views. They would have laughed you out of the building if you told them a single person could ever produce compelling enough video content and get at many viewers.
