IDC said global shipments of wearable devices reached 21 million units in the third quarter of 2015, up 197.6 per cent from the 7.1 million shipped in the third quarter of 2014. Chinese vendors are grabbing market share, with Xiaomi a strong contender to take the number two spot from Apple and XTC beating South Korea's Samsung to the number five position. Smart watches from the likes of Apple, Motorola, Pebble and Samsung have drawn increased attention to the market, but this has not dampened interest in fitness trackers, IDC noted. Indeed Fitbit maintained its leadership of the worldwide wearables market with a market share of 22.2 per cent, shipping 4.7 million fitness trackers in the third quarter of this year. Release
