Brick-and-mortar retail giant Best Buy is for the second time expanding a pilot program that began in late May of last year, bringing Apple computers to 200 of its stores by this fall. "We'll be expanding our relationship with Apple in 2007," said Best Buy president Brian Dunn during the company's latest earnings conference call. "We'll be offering Apple computers in 200 stores by this fall." The nation's largest consumer electronics retailer began with a select number of stores to test drive selling Mac systems, which grew to 50 stores across the U.S. in mid-October. The most recent pilot expansion reveals the success of its predecessors, increasing the exposure of Mac computers at Best Buy locations by three-fold. Circuit City also said it would begin selling Macs in a small number of its stores in the Eastern U.S. in early September to test the waters of Mac sales in its retail outlets.
