12% of Internet, App Activities Occur on Mobiles

The amount of time people spent using mobile devices for activities such as Internet and app use, gaming, music and others has more than doubled in the past two years, according to eMarketer.

As a result, 12 percent of total time spend consuming media, using apps and the Internet now happens on mobiles. 

In 2012, the amount of time U.S. consumers spent using mobile devices excluding talk time, grew 52 percent to an average of 82 minutes per day, up from just 34 minutes in 2010, eMarketer says. 

Time spent with "online" (non-mobile) apps and activities grew 3.6 percent to an average 173 minutes per day, compared to 7.7 percent growth in 2011 to 167 minutes per day.

Mobile will have the higher growth rates, in part because mobile usage starts from a low installed base, and in part because more mobile devices are being used for Internet and mobile app activities.
