Amazon: Kindle Sales Quadrupled on Black Friday
Amazon said Monday that sales of its Kindle devices increased fourfold over 2010 on Black Friday. The huge sales can likely be attributed to both the greater number of different Kindles available and much wider retail availability, as well as the presence of the Kindle Fire tablet.
The company also said that the Kindle Fire has been the top-selling product across Amazon ever since it was introduced in September.
As usual, Amazon did not release exact sales figures for any of its Kindle models.
