Amazon has released a large amount of data about online sales in 2012, with lots of factoids and vague figures for digital downloads, purchases, and product shipments. And the biggest piece of data revealed by the company was the number of packages it sold on the peak day of 2012.

On Nov. 26, Amazon sold 26.5 million items worldwide across all product categories. That equates to a whopping 306 items per second, a new record, according to the company.

Amazon also shed some insight into ebook purchases for the year. For instance, it revealed that 23 of its self-publishing (Kindle Direct Publishing) authors each sold over 250,000 copies of their respective books in 2012. And the most gifted ebook sold during the holiday season? That would be number wizard Nate Silver’s The Signal and the Noise: Why So Many Predictions Fail-but Some Don’t.

Ultimately, there isn’t much useful information for shareholder to determine how well Amazon is doing in regard to its digital purchases. But the new data did share lots of information about physical product shipments. (Amazon customers purchased enough copies of the Fifty Shades trilogy by E.L. James, including Fifty Shades of Grey, Fifty Shades Darker, Fifty Shades Freed and the trilogy box set, to create a stack 445 times taller than the Seattle Space Needle.
