Prime Day was Amazon's biggest sales day ever

The numbers are in, and Prime Day has proven to be the biggest sales day ever for Amazon (NASDAQ:AMZN). The second annual event saw a 60 percent increase in orders globally and a 50 percent increase in the United States compared to last year.

It was also the biggest day ever for Amazon devices globally and a record Prime Day for each Amazon device category, including Fire TV, Fire tablets, Kindle e-readers and Alexa-enabled devices, according to the company.

Amazon sold more than 2.5 times as many Amazon Fire TV devices compared to last year's Prime Day, and 2.5 times as many Echo Bluetooth speakers compared to that device's previous record day. The Fire TV Stick was the best-selling Amazon device.

Electronics once again proved to be a big seller, with more than 90,000 TVs, 200,000 headphones and 14,000 Lenovo laptops bought.  

Mobile engagement was up, with more than 1 million shoppers using the Amazon app for the first time on Prime Day to shop and watch deals. Prime members purchased on average one Alexa-exclusive deal per second during Prime Day using their voice. Alexa is the virtual voice assistant inside Echo that responds to verbal commands.

Marketplace sellers also reported strong sales during the event, according to an emailed statement.

"Prime itself is the best deal in the history of shopping, and Prime Day was created as a special benefit exclusively for our Prime members," said Greg Greeley, VP, Amazon Prime. "We want to thank our tens of millions of members around the world for making this the biggest day in the history of Amazon. We hope you had as much fun as we did. After yesterday's results, we'll definitely be doing this again."

Prime Day was Amazon's second annual single-day summer sale, with new offers and deals launched every five minutes and available exclusively to members of Amazon Prime. The retailer has never released the exact number of Prime members, saying only that there are "tens of millions."

One independent estimate put that figure at more than 54 million.
