The total number of U.S. Internet users passed the 150 million mark for the first time ever, according to estimates released Tuesday by comScore Media Metrix. The online researcher also found that the
total amount of time spent by Americans on the Internet grew by 3 percent in September, although the month of September is one day, or 3 percent, shorter than August. This increase in time spent
online was driven almost entirely by the university population returning to campus and their computers. In September, there were three new entrants to comScore's Top 50 Properties ranking" Verisign,
Emode.com and Columbia House.
