The co-founders of internet search leader Google Inc are selling 10 million shares worth $5.5bn at current prices, AP has reported. Larry Page and Sergey Brin will each sell 5 million Google shares during a five-year period that will commence with the first trade. The sales will occur periodically to lessen the chances of hurting Google's stock price. Page and Brin will remain Google's most influential shareholders, although they will be losing some of their clout.
