Amazon announced this morning that 2011 was its Kindle line's best holiday season to date, with over one million devices sold per week throughout December. Amazon seems particularly proud of how well received its Kindle Fire has been, citing the device's title of #1 best selling, most wished for, and most gifted device on the site for the past 13 weeks. The popularity of the Kindle line, Amazon says, has given rise to the growth of its Kindle Direct Publishing program, which generated the #1 and #4 titles on Kindle's best selling list this year. Just how well the Kindle line, and the Kindle Fire in particular, is selling is still a mystery, as Amazon has failed to release any hard numbers for holiday sales. Read into that tidbit as you wish.
