The company's stats reportedly show that November 29 (Cyber Monday) was Amazon's busiest day of 2010. On that day, worldwide visitors bought an average of 158 items every single second, totaling a "record-breaking" 13.7 million items sold.
"According to comScore, overall online spending in the United States surpassed $1 billion on Cyber Monday in 2010, up 16 percent versus [a] year ago. Clearly, Amazon took a huge piece of that particular pie," writes TechCrunch.
Amazon also revealed that the third-generation Kindle e-reader was the most popular holiday item, based on the number of units ordered.
Thanks to the Kindle 3's strong sales this year, Amazon dubbed the device its worldwide bestselling product of all time. Previously, Amazon's bestselling item had been "Harry Potter and the Deathly Hallows."
"Kindle's $139 price point is a key factor -- it's low enough that people don't have to choose," said Jeff Bezos, Amazon.com founder and CEO in a press release.
Though Amazon did not outline the Kindle's exact sales figures, Business Insider states that Amazon is probably "on pace to sell 8 million Kindles this year."
