In the past three years the volume of spam messages has increased at a staggering rate. In 2003 we reached the 50% threshold, which means that now at least half of the emails sent across the Internet are spam.

If the volume of spam continues to increase at the rate of previous years, at the end of 2004 spam messages will be nearly 80% of the total.

The graph on the right shows this progression. The non-red area represents our estimate, based on the current trend.
