A study by the University of Southern California shows 21 percent of adult Internet users with children believe their kinds spend too much time on the Internet. In 2000 it was only 11 percent but that's still way less than the 49% who think their children watch too much TV.
About 80 percent of the children say the Internet is important for schoolwork, although three-quarters of the parents say grades haven't gone up or down since they got Internet access.
Forty-seven percent of the adults say they have withheld Internet use as a form of punishment. Banning television is still more popular, reported by 57 percent of adults surveyed.
The study, meanwhile, found that although only 27 percent of cell phone owners use them for text messaging, photo transmitting and other nonvoice functions, the figure grows to 54 percent among those 18 to 24 and 45 percent among those under 18.
