TV Continues to represent 99 percent of viewing on all screens, according to the Council for Research Excellence. Contrary to some recent popular media coverage suggesting that more Americans are rediscovering "free TV" using the Internet, computer video tends to be quite small with an average time of just two minutes (a little more than 0.5 percent) a day.
Despite the proliferation of computers, video-capable mobile phones and similar devices, TV in the home still commands the greatest amount of viewing, even among those ages 18 to 24, the Council says. This appears to refute a common belief that Internet video and mobile phone video exposure among that group (as well as the 25 to 34 cohort) were significant in 2008.
Consumers in the 45 to 54 age group average the most daily screen time (just over 9.5 hours). The study also found the average for all other age groups to be "strikingly similar" at roughly 8.5 hours
Even in major metropolitan areas where commute times can be long and drive-time radio remains popular, computer use has replaced radio as the second most frequent media activity. Radio is now the third most popular media format while and print media ranks fourth.
Live TV led all video usage by a large margin, followed by DVDs, with DVRs third.
