Residents of Half Moon Bay California, there's no need to be worried. That large roar you hear is likely the collective cheers coming from GoPro's HQ. The Californian company just announced a new round of funding and that Best Buy is now selling most of its product line based around the popular HD Hero camcorder. The founding comes from Riverwood Capital, Steamboat Ventures, Sageview Capital, Walden International and U.S. Venture Partners. The amount wasn't disclosed, but GoPro's Rick Loughery indicated to me in an email that "it's a lot" and the company is growing rapidly and now employes over 80 people rather than the 14 this time last year. The funding will also be used to take the wearable camcorder to international markets. The HD Hero is already without question one of US' favorite action camera and GoPro's other announcement regarding Best Buy will further expand its popularity here in the states.
