How big was YouTube back in the day?

I remember watching videos like this and thinking like a lot of ppl watched them but i guess not

I just remember some of the biggest things would make it. Not every little thing. But 08 youtube was still mostly just regular folk uploading personal videos of them doing stupid stuff. Not the money making juggernaut it is now.
