Wearables device market grew 200 percent in first quarter, led by Fitbit

In the three months leading up to the April release of the Apple Watch, the wearables market continued to show strong growth. The worldwide wearable device market recorded its eighth consecutive quarter of steady growth in the first quarter in 2015, with vendors shipping a total of 11.4 million wearables, according to research firm IDC. That was a 200 percent increase from 3.8 million in the year-earlier quarter.

"Bucking the post-holiday decline normally associated with the first quarter is a strong sign for the wearables market," IDC research manager Ramon Llamas said. He said the growth demonstrated growing consumer interest and tech companies' ability to deliver compelling products and experiences. Demand from emerging markets is also on the rise. Now that the Apple Watch has hit store shelves, IDC is predicting that the wearables landscape will shift significantly. "The Apple Watch will likely become the device that other wearables will be measured against, fairly or not," Llamas said. "This will force the competition to up their game in order to stay on the leading edge of the market."
