The error bars indicate the 95% confidence intervals of the estimated hours per day. Total screen time in 1997 included time spent on any activity while watching television programs or videotapes plus time spent on electronic video games and home-computer–related activities. Total screen time in 2014 included time spent on any activity while using television, videotapes, digital video disc, game devices, computer, cell phone, smartphone, tablet, electronic reader, and child’s learning devices. Television time refers to time spent on any activity while watching television programs using a television set (rather than using videotapes, digital video disc, or other devices). Mobile device time refers to time spent on any activity while using cell phone, smartphone, tablet, electronic reader, and child’s learning devices.
