U.S. government agencies spend an overwhelming amount of their annual information technology budgets simply to maintain old and out-of-date systems. As a result, the amount of money available for investing in modernizing IT keeps shrinking, thus depriving vendors of major marketing opportunities at the federal level. The official federal IT budget has remained at about $82 billion per year for several years. However, that figure does not cover all agencies -- intelligence and the U.S. court system are notable exclusions -- and some estimates project annual IT spending above $100 billion.
