TV viewing is among the most significant features of childhood. In the past generation or two, new technologies have made media viewing more ubiquitous and frequent: 30% of children eat regularly in front of TV, one-third under 6 have TVs in their bedrooms, and 30% make TV part of bedtime routines. By the age of 2 years, 90% of children watch TV or videos regularly. Among those who watch, average viewing is 1.5 hours daily by age 2.
