Some of the top YouTube channels are said to make over $10,o00 per month. Channels like Shane Dawson, Ray William Johnson and Fred are some of the top money makers on youtube.
There are two types of partnerships with youtube. One is a Full partner, which is what is listed above. They are able to have more control over their channel page and customize it. They can also add custom thumbnails to their videos and their ads get instantly approved on the videos they upload.
The 2nd kind of partner is the Youtube individual partnership program. The IVP allows youtube users to display and make money only some of their videos. They are not able to customize anything or have any extra advantages than a standard channel. However, they will earn money into their adsense account which could lead to big bucks.
