Forrester has today revised its previous estimates of global IT spending with a new figure of 6%. A previous report from the company estimated 9% growth for 2008.

"Our forecast is based on a mild recession in the US economy in the first two to three quarters of 2008," said Forrester Research Vice President Andrew Bartels. "While it is by no means certain that the US economy will in fact experience a recession, the risks of one are high enough to justify a more conservative outlook for the IT market.

The US remains the biggest user of IT goods and services but slowing growth across the pond will increasingly be felt around the world. US spending growth is estimated at 2.8%, down from its previous forecast of 4.6%.
