It's not a question of how many people watch your videos though, its a question of where the real talent lies. Rebecca Black had no talent at all and millions of idiots watched her video.
On that note of people watching videos.... I have to say THIS ^^^
and add the fact that when Michael Jackson and Whitney Houston where doing videos, there wasn't even the internet, so nobody can measure how many people watched their videos, in fact I bet that if Youtube existed when Jackson's videos first came out, they would all be on a point that no one would ever reach in terms of viewers.
