Worldwide IT services revenue totaled $672,3-billion in 2006, a 6,4% increase from 2005 revenue of $631,8-billion, according to Gartner. 

"Core business process outsourcing (BPO) services had a strong showing in 2006," says Kathryn Hale, research vice-president for Gartner¹s worldwide IT
services group. "These process management services grew 8,6% worldwide, and several market leaders grew faster than the overall market. Still, development and integration services represent the backbone of IT services, accounting for 30% of the market in 2006."
Across all IT services, IBM continued to be the worldwide market leader, but its growth rate was below the industry average. EDS and Accenture were the only vendors in the top six that experienced revenue growth rates above the overall market average. Market share for 13 of the top 20 vendors dropped in 2006.
While global sourcing makes the location of a provider¹s headquarters increasingly less relevant, Gartner tracks this information for more than 400 vendors that collectively account for more than 70% of end-user spending worldwide.
While India-based vendors' IT services revenue grew 33,3% in 2006, these companies earned only 3% of revenue tracked, while US-based vendors earned 57% of that total.
"Without significant acquisitions, it would take India-based vendors many years to reach even half the revenue of US-based vendors," says Hale
