U.S. Census Bureau compiles an annual "Information and Communication Technology Survey."  Click the "Historical Data" link to get the annual reports starting in 2003.  Click on the "Summary of Findings" link for graphs and more detailed data about the IT expenditures (purchases vs. rental, software vs. hardware, ranking of industry sectors, detailed breakdown of industry sectors, retail vs. wholesale).
