The Ball State study found that the average American adult was exposed to five hours and nine minutes of live TV each day, almost 15 minutes of TV via a DVR device and 2.4 minutes of video on the computer.
The average person should watch 30 to 60 minutes a day. An hour is enough for four fifteen minute episodes, and enough for two thirty minute episodes.
