Media consumption continues as an integral part of the American lifestyle. According to a USC report released last week, Americans are voraciously consuming media via TV, radio, phone and computer, which led to an average consumption of 63 gigabytes per person per day last year. In 2012, total U.S. media consumption averaged 1.46 trillion hours, an average of 13.6 hours per person per day. By 2015, average media consumption is expected to reach 15.5 hours a day per person.

“In comparison, U.S. media consumption averaged 33 gigabytes per person per day in 2008. That year, Americans viewed and listened to media for 1.3 trillion hours, an average of 11 hours per person per day,” explains The Los Angeles Times.

These numbers are expected to increase in the future. By 2015, it is expected that Americans will collectively consume 1.7 trillion hours of media, which is approximately 15.5 hours per day per person.

Other figures will increase in 2015 as well.

“Mobile messaging hours, which last year accounted for about 9 percent of voice call hours, will double to more than 18 percent of voice hours, a year-over-year growth rate of more than 27 percent,” reports LA Times.

Also, the number of hours spent viewing videos online will increase. While this number was at less than 3 hours a month in 2008 and about 6 hours per month last year, it will probably reach 11 hours per month by 2015.

“Traditional media continues to dominate our daily media consumption, with TV and Radio contributing 60 percent of the hours,” writes James E. Short in the report’s executive summary. “New digital sources, however, are having major effects on most forms of media consumption. Over half of all media bytes are now received by computers, with mobile computers the most rapidly growing segment. In 2008, mobile computers accounted for approximately 3 percent of all bytes, by 2013 it is almost 10 percent, representing a year over year growth rate of 27 percent.”

The report comes from The Institute for Communication Technology Management (CTM) at the University of Southern California’s Marshall School of Business. The press release offers additional details.
