The CIOZone 100 looks at the 2007 revenue and profit of the U.S.'s largest public technology companies.
To come up with the list, CIOZone looked at companies by their SIC standard industrial codes and put on our list those that we thought were most relevant to chief information officers. We made some judgment calls to winnow down the ensuing list. Thus, while we left in Intel and Advanced Micro Devices, we eliminated most other component makers on the assumption that CIOs rarely if ever buy from them directly. With the exception of Cisco, we also took out most makers of communications hardware, because communications equipment is arguably a separate industry (one we plan to examine in an upcoming ranking). For simplicity's sake, we eliminated any company that isn't based in the United States. SAP is the one exception we made to that rule; the German company is just too important to the average CIO not to be included.

Our report uses 2007 calendar-year results, eliminating the apples-to-oranges period comparisons that would otherwise arise because of when many companies' fiscal years end. In the case of companies that don't have quarters ending in December 2007, we used the closest quarter we could find. Thus, in the case of some companies, their 2007 revenue and profit data may actually reflect results for the 12-month period ended on Nov. 30, 2007, or on Jan. 31, 2008.
We used a cut-off of Feb. 20, 2008 for our data-gathering, meaning if a company reported results after that, the results aren't reflected in the lists published here.
