I've never heard of him, what kind of videos does he do?

I'm guessing the same reason anything is popular. Because specific people find him entertaining. Much like specific people like DOA, specific people don't. etc. Such is life heh.

alot of people enjoy screaming at the screen for millions of views, but theres also people taking their pants off and rubbing eggs and expired food on their legs, or a group of people making batshit crazy recipes. Honestly there are too many youtube users that do the same shit, like screaming in front of a screen for views, i mean Felix (pewdiepie) was really funny for a while but, it got old quickly
