Amazon.com Inc, the largest internet retailer, said it sold "well over" 1 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 percent from a year earlier in the period from 25 November to Christmas Day, Amazon said.
