The 2009 Best-Sellers report features the best-selling vendors in systems, peripherals, security, storage, software and networking through distributors in 2008, as aggregated by The NPD Group for Everything Channel. As one might expect, Hewlett-Packard and Cisco Systems were all over the place, combining to claim the most market share in seven of the 20 product categories.
HP also finished in the top five in eight categories, evidence of its breadth with channel partners. The following slides illustrate the top companies in each category. Each slide indicates the company name, its percentage share of all revenue in that product category through distributors in 2008 and the market-share percentage change from 2007. The vendor with the most share is highlighted in blue, while the company with the most share shift is highlighted in red.
