Shane Dawson, Colleen Ballinger, GloZell, Rebecca Black, and Lucas & Jenny. I'm gonna have to get into Shep689, they look like they have cute videos.
And for those asking if YouTubers make money, believe me, they do. They can make anywhere from 100K to over a million. The key is ad revenues and product placements. The reason why all the big name YouTubers always remind people to Like, Favorite, and Subscribe is because the more subscribers they have = more cash in their pocket. Even the younger YouTubers like Rebecca Black and Lohanthony are collecting coins left and right.
