By Malathi Nayak SAN FRANCISCO (Reuters) – To imagine how YouTube might one day become a money-spinner for content producers, consider the power of the irreverent video gamer and online star PewDiePie over his young, free-spending audience. Each time the wildly popular YouTube impresario has donned Razer headphones in one of the many zany videos that feature him playing games, the product has sold out. Its incredible that YouTube personalities are coming up … and I think it can only grow. PewDiePies uncanny trendsetting talent highlights the potential that content related to video games holds for Google Inc as it looks for ways to build its YouTube video platform into a powerful new revenue stream. Just last week Walt Disney Co agreed to fork over as much as $950 million to buy Maker Studios, one of YouTubes largest production and distribution networks.
