Cdw Corp
A multi-brand IT solutions provider, CDW sells more than 100,000 hardware, software, and service products from over 1,000 vendor partners to business, government, education, and healthcare customers across the US, UK, and Canada. It began in 1984 when Michael Krasny placed a small newspaper ad to sell his personal computer, got an overwhelming response, and started reselling computers from his Chicago apartment under the name Computer Discount Warehouse—the initials that became CDW.
