With Amazon taking customers from specialty retailers on the basis of price questions are raised about the future of Best Buy. Best Buy competed by having tech savy salespeople and moderately lower prices. Borders lost sales to Amazon. Now this is happening in electronics as Amazon increases share. Customers can visit Best Buy to check out electronic goods and then buy on Amazon for the lower price, making Best Buy Amazon's showroom. Amazon's electronics and nonmedia revenue went up by 66% in 2010 to $18 billion. With Sony selling through Costco another advantage is eroding. Even with Circuit City out of the market Best Buy was losing market share (December 2010 figures show) in the key television and computing segments.
