U.S. online users ages 12 and older spent 6.1 hours daily on video-based entertainment, according to a survey conducted in June 2008 by Solutions Research Group.

According to the survey, about four hours per day are spent on traditional television, including live, digital video recorder and video-on-demand viewing. Time on video games, online and PC video, DVDs and video on mobile devices totalled about two hours, eMarketer reported.

The research company estimated total hours with video-based entertainment will increase by about one-third to nearly eight hours per day on average by early 2013.

Although total video-consuming time is expected to go up, most of it will go to online video, not TV, eMarketer reported.

Another study from Deloitte also indicates the shift away from TV to the Web. About 70 percent of respondents in the Deloitte's survey said the computer has become more of an entertainment device compared to the TV.

Among the youngest group, 80 percent see the computer as an entertainment device more than TV. However, it is surprising that over half of the oldest respondents said so, according to eMarketer's recent study “Online Video Content: The New TV Audience.”
