$2.3 bln was spent on Web services in 2004, $14.9 bln by 2009

According to IDC, the vendor community has shifted its primary attention from Web services creation to that of more robust consumption, with security, management, messaging and event processing, and the assembly of services into composite solutions as key focal points. Leading adopters are evolving proof-of-concept implementations into more robust deployments. IDC estimates that $2.3 bln was spent worldwide on total Web services software in 2004, more than double the amount from 2003. IDC expects spending to continue to increase dramatically over the next 5 years, reaching approximately $14.9 bln by 2009.
