Go Pro's sales jumped by 38.1 percent to $244.6 million for the second quarter, with growing demand for its latest products as well as a rise in contents, which are themselves driving extra sales. Go Pro, a Californian company selling small cameras that people strap to themselves to record their exploits, went public in June. The quarter was further marked by the launch of new accessories and an entry into new vertical markets, such as hunting and fishing with the Sportsman Mount. Go Pro's gross margin advanced to 42.1 percent, up by 10 percentage points compared with the same quarter last year. However, its net loss attributable to stockholders widened to $19.8 million, compared with a loss of $5.1 million for the same quarter in 2013.
