2001
CXOs are top executives who have "chief" in their title — chief executive officers, chief financial officers, chief information officers and so on. No middle managers need apply.

According to David R. Curry, Exec! Publisher and Unisys Vice President, Corporate Public Affairs: "Our goal with Exec! is to become the destination website for senior managers. We know that executives at the "CxO" level - CEOs, COOs, and CFOs - are venturing out onto the Web. We know that they are expecting to find a wealth of information, but instead encounter chaos. What they don't find is an intelligent or efficient way to get at what might be useful or interesting. Exec!, with its special CxO Resources service, identifies, evaluates, organizes and presents the best Web content and resources for CxOs.
