Dive summary: 

• A report from eMarketer shows that U.S. adults now spend an average of five hours and nine minutes each day with digital media; the average amount of time spent watching TV is four hours and 31 minutes. 
• This is the first time digital media time has surpassed television viewing; the amount of total time spent consuming media in any form—TV, digital, radio, and print—is up overall, with the average U.S. adult devoting 11 hours and 52 minutes each day. 
• The rise in digital consumption has been driven by the increased used in mobile devices; according to the report, U.S. adults now spend an average of two hours and 19 minutes a day using their mobile devices for functions other than phone calls. 

From the article: 

"The figures account for time spent with every unique medium, regardless of the overlap in consumption. Thus, people watching a basketball game while simultaneously continually tweeting about it from their tablets would count for two hours spent watching TV and two hours spent using a mobile device."
