Does TikTok have the long form content that YT is also associated with? Otherwise I would say "disrupted" is a generous term

Long form YT is a gold mine of

- documentaries (hobbyist and professional)

- informative content (literally any hobby you can imagine from gardening to warhammer to free diving)

- educational content, similar to above but world class institutions hosting their lectures for free

- musical content, live performances ranging from tiny amateur bands to top names and performances of now dead artists

- sports events, the entire 6 hour+ Wimbledon 08 final is there

I can go on but for a while now I have seen YouTube as the Video Internet (where web 1.0 was the Document Internet).
