That said, i also think production value in popular channels has really skyrocked the last few years. We've entered kind of a golden age for user generated content, for better or worse. It is very entertaining but very much more addicting.
For example, i watched a guy for years who reviewed classic synthesizers and made silly songs. He has recently made an entire 2hr documentary on the history of ARP synthesizers with engineer interviews and everything! It is like some Ken Burns level stuff https://www.youtube.com/watch?v=l31RXiVSI9s Nothing on youtube existed like this a few years ago. It is an amazing world we live in now.
