When the television is always on: Heavy television exposure and Young children's development

In American homes, the television is on approximately 6 hours a day on average. Yet little is known about the impact of growing up in the near constant presence of television. This study examines the prevalence and developmental impact of "heavy-television" households on very young children aged 0 to 6 drawn from a nationally representative sample (N = 756). Thirty-five percent of the children lived in a home where the television is on "always" or "most of the time," even if no one is watching. Regardless of their age, children from heavy-television households watched more television and read less than other children. Furthermore, children exposed to constant television were less likely to be able to read than other children.
