IDC predicted that global shipments of wearable devices will reach 110 million by the end of 2016, with 38.2 per cent growth over the previous year. The research company added that an expanding line-up of vendors combined with fast-growing consumer awareness and demand will generate double-digit growth throughout the 2015-2020 forecast period, culminating in shipments of 237.1 million wearable devices in 2020. Watch and wristband shipments will reach a combined total of 100 million shipments in 2016, up from 72.2 million in 2015. Other form factors, such as clothing, eyewear, and 'hearables' (smart earphones), are expected to reach 9.8 million units in 2016 and will more than double their share by 2020. Report
