US: Half of time spent online is on mobile devices

Mobile devices (smartphones, tablets) now account for 51% of US’ adults total time spent with the Internet.

Mobile has become so important to consumers’ lives that for the first time, time spent on nonvoice mobile activities in the US overtakes time spent online on computers. The shift from desktop to mobile, whether smartphone or tablet, is happening across a variety of activities, including digital video viewing.

However, the share of mobile in the total US digital spending  is still tiny compared to the share of online time spent. Mobile advertising has a very promising future.
