Yep, my entertainment is 90% YouTube and the rest some show. On YouTube I find everything: from a dude that does reviews of air filter for cars to somebody explaining some obscure Japanese woodworking techniques to the omniscient Indian dude that explains complex programming concepts. If there was fragmentation I wouldn't be even able to find stuff, like in the early days of the internet that you knew the website existes because somebody shared the URLs in some usenet or some forums, before search engines became a thing.
