While declining, as always, to release specific sales figures, Amazon said the Fire HD has been at the top in all three categories since it was introduced 15 weeks ago.
The non-HD Kindle Fire, the Kindle Paperwhite and regular Kindle e-readers joined the Fire HD as the top four best-selling devices for Amazon across the globe for holiday shoppers, Slash Gear reported Friday.
With the sale of the devices came a jump in demand for downloadable digital content as well, Amazon said, with more than 23 million movies, TV shows, games, apps, songs and other content downloaded on Christmas Day.
It was not just a holiday gift phenomenon, the company said, noting that back in October the Kindle tablet was its best-selling product in all of its global markets.
