Amazon (AMZN) on Tuesday announced that sales of its popular line of eReaders and tablets doubled over Black Friday and Cyber Monday. While the online retail giant was quick to announce its latest milestone, it failed to give actual sales figures yet again. Instead, Amazon said that this past weekend was its best ever for the Kindle family and Cyber Monday was the single best day for Kindle sales worldwide. The newest Kindles have remained on the top four spots on the company’s bestseller list since launching nearly three months ago. Amazon notes that nine out of the top 10 best-selling products listed on its site worldwide have been Kindles, Kindle accessories and digital content.

“Kindle e-readers and Kindle Fires have held the top 4 spots on the Amazon worldwide best sellers list since launch, and that was before the busiest shopping weekend of the year,” said Dave Limp, Vice President, Amazon Kindle. “We’re excited that customers made this Black Friday and Cyber Monday the best ever for Kindle worldwide—Cyber Monday was the biggest day ever for Kindle sales, and we’re looking forward to millions of customers opening a new Kindle this holiday season.”
