The beauty of the Web isagreements that it gives marketers much more flexibility than most fairly rigid traditional media. Japan and countries like Canada, Australia and parts of S. America are in the works. In terms of usage days, however, work had 13.1 avg usage days in May versus 11.6 for home. The key differences are significant, but many stem from some fairly predictable patterns. I mentioned AOL's unique strength among home users - Yahoo is strong during work hours.
Shopping is very strong at home, but often more buying is is split more evenly.
Home usage is very strong during evening and, to a lesser degree, weekend hours. News sites, for example, get a lot of morning traffic. Researchers at Xerox did a traffic distribution study about a year ago, looking at 120,000 Web sites. In their sample, the top 5 percent of sites got 75 percent of the traffic. We see a similar trend but not nearly so strong.
