Amazon had some serious trombone action going on last year — what with all the horn tooting it did about Kindle Fire demand. Turns out Amazon was on to something, as the company has apparently grabbed the No. 2 spot from Samsung for tablet sales in the last quarter, according to research firm IHS iSuppli. Based on its numbers, Amazon sold 3.89 million tablets during the fourth quarter, eclipsing Samsung’s 2.14 million units. The numbers equal a 14 percent share of the tablet market for Amazon while Samsung grabbed an 8 percent share, down from 11 percent in the third quarter. The brisk sales came at a price for Amazon, which saw fourth-quarter profits drop since it sold Kindle Fire tablets at a loss. Amazon’s tablet sales also were still below the 15.4 million iPads sold by Apple for the period. All the competition is apparently taking a bite out of Apple’s market share, however, which fell to 62 percent in 2011, compared to 87 percent in 2010. Samsung did manage to hold on to the No. 2 spot for the year, but with rumors already swirling about new iPads plus the Galaxy Note 10.1, the tablet wars aren’t likely to cool off anytime soon.
