Men consume more media than women - across all categories except magazines - by an average of seven hours per week, according to a Forrester report cited by ClickZ. On average, men spend 10.2 hours on a PC per week, compared with the 8.5 hours that women spend. Men spend 6.7 hours of that time online, whereas women spend 5.3 hours. The report is aptly titled "Men are from CNET, Women are from iVillage." Online, women lead men only in instant messaging - but by a slim margin.

Men tend to surf for news, magazines, finance, job and career information - and visit discussion boards and comparison-shop. Men are 60 percent more likely to research financial data than women, for example.

Women tend more to get movie information, play games, share photos, and use online phone directories. They are more inclined to use the web to search for bargains and download coupons.
