According to a recent report from the NPD Group, San Francisco-based Fitbit shipped 67 percent of all activity tracking devices in 2013. The company’s devices also accounted for 77 percent of the “full body activity trackers” shipped during the five weeks leading up to Christmas. That’s up from about 60 percent for 2012′s holiday season, according to Fitbit. NPD also estimated that the digital fitness category is now a $330 million market.
