Well, we didn't think the day would come. But rumors have arised which state that Google are beginning to work with a small number of popular YouTube video channel operators on a pilot program which could result in paid subscriptions as early as this spring.According to reports, Google plans to team up with YouTube partners like Machinima, Maker Studios and Fullscreen to offer up paid subscription tiers, as well as bringing in new content brands. Google began offering YouTube feature videos which you could rent in 2010, but allowing channels to charge money to access their content could turn YouTube into a online alternative to a cable TV network, if enough people actually sign up for them.
