Running your own YouTube channel seems to be the next big thing since several people, who are well established in their careers, are now quitting their jobs and starting a YouTube channel and not just running it, making a decent living out of it. Coming to the question, I do not believe that there is any limit to the money you can make from YouTube just like there is no limit to the number of views you can get on the videos you upload to YouTube. The more views your videos get, the more money you make. One of the most famous YouTuber, Jenna Marbles, made hundreds of thousands of dollars via the videos that she uploaded on her YouTube channel. Once you have linked Google Adsense to your YouTube channel, you get almost 70 percent of the money paid to YouTube by advertisers on every view of 30 or more seconds of the advertisement. So that way, the more viral your videos are or the more subscribers you have to your channel, the more people watch your videos, the more ads will be viewed and the more money you will make. On video ad on YouTube typically costs around 0.18 USD so you can image how much money there is in the YouTube channel business.
