Sad, but true.
"We were very interested to discover that the increase in Internet use over the last 10 years has eaten into television viewing less than expected," said Norman Nie, director of SIQQS. "Time online seems to come more out of family discretionary time."
For the average respondent, an hour of time online reduces the amount of time spent with family more than twice as much (23.5 minutes) as it limits daily TV viewing (10 minutes). This amounts to 70 minutes less time spent per day with family, versus c. 30 minutes less time watching television. The study also found the average surfer gets 8.5 minutes less sleep per day due to time spent online.
How they get these statistics... god knows. :)
