PALO ALTO, CA--(Marketwire - April 7, 2008) - A new study showing market size, market share, and four-year forecasts (2008 - 2012) for all core market segments tracked by The Radicati Group, Inc. is now available.

The study shows that the worldwide installed base of active mailboxes will increase from 2 billion in 2008 to over 2.7 billion in 2012. This represents an average annual growth rate of 8% over the next four years.

In 2008, 78% of worldwide email traffic will be spam. This figure will increase steadily over the next four years, totaling 83% in 2012. However, only 56% of spam traffic is actually being delivered to end users in 2008 -- the rest is blocked by network or gateway spam filters. This figure will decrease to 53% by 2011, as spam filters increase in efficiency.

As demand for more efficient means of communications grows, so does the market for real-time messaging. The Instant Messaging installed base is expected to grow from 1.2 billion in 2008 to over 1.9 billion in 2012.
