For the first time, U.S. adults are using mobile devices for the majority of time they spend on the Internet. The latest Internet Trends report from Silicon Valley venture capital firm Kleiner, Perkins, Caufield and Byers says American adults have spent 5.6 hours per day on the Web this year, up from 5.3 hours in 2014. Of those 5.6 hours, mobile devices are being used 51 per cent of the time, while desktop/laptop accounts for 42 per cent and other connected devices for 7 per cent. In 2008, mobile devices accounted for only 12 per cent of daily Internet usage.
