Amazon.com Inc, the largest Internet retailer, said it sold "well over" one million Kindles a week in December, with record demand led by its Kindle Fire tablet.
The top three sellers on Amazon's website were the Kindle Fire and two electronic readers, the Kindle Touch and Kindle, Seattle-based Amazon said on Thursday in a statement. Gifting of Kindle books rose 175 per cent from a year earlier in the period from November 25 to Christmas Day, Amazon said.
The company introduced Kindle Fire, which has a 7-inch display and sells for less than half the price of Apple Inc.'s least-expensive iPad, on September 28 in a bid to erode Apple's dominance. Amazon is releasing a Fire update to improve performance, make touch navigation easier and let users choose what items are displayed, after some users complained.
Amazon fell 3.2 per cent to $168.35 at 9:38 am New York time. The shares declined 3.4 per cent this year before on Thursday.
