The surge in mobile advertising is chiefly attributable to the fact that consumers are spending more and more time with their tablets and smartphones. According to eMarketer’s latest estimates, US adults will spend an average of 2 hours 51 minutes per day with mobile devices this year. In 2013, daily time spent on mobile devices and on desktops and laptops was equal, totaling 2 hours 19 minutes, but this year, time with desktops and laptops will drop slightly to 2 hours 12 minutes, while mobile time will increase significantly. TV remains by far the largest beneficiary of adults’ media time, at 4 hours 28 minutes in 2014, hence its persistent lead as the top category for advertising spending. Read the rest at eMarketer.
