In its "Information Technology 100," BusinessWeek ranked CDW No. 2 in the category of Distributors. "CDW is producing record results in the face of this economic downturn," said John A. Edwardson, chairman and chief executive officer of CDW, a leading provider of technology products and services to businesses, government agencies and educational institutions. "To improve further on this performance, we will remain focused on superior customer service. This means recommending the right technology products and services for our customers and getting it to them quickly, in most cases the next day." For the "IT 100" list, BusinessWeek selects and ranks companies based on a number of criteria, including revenue growth, total size, shareholder return and return on equity.
