Shift: "[According to the Computer Industry Almanac] Approximately 43 percent of the estimated 259 million users worldwide live in the States; an online population greater than the total of the other 14 nations listed in the Top 15. The world-wide online population is expected to hit 490 million by 2002....the US will comprise a third of users by 2002, and 27 percent by 2005."
Another interesting thing to ponder: 490 million people will still only be 7.9% of the world's population.
