The time that is spent by teens online is actually rather limited, with 12 to 17 year olds spending, on average, only 13 hours per week on the Internet (compared to a weekly average of 19 hours for online adults), and that number has not increased since Ipsos last measured online teen behaviour in 2004. There are at least a couple of factors that might account for the relatively little time teens spend on online. One is the influence of parents on teens’ Internet use – over one-half (54%) of online teens surveyed reported that their parents place time limits or curfews on when they can access the Internet. The other is that only a minority of teens (37%) agree that using the Internet is an important part of their day (compared to 51% of adults).
