Amazon Prime sells 3 million memberships just before Christmas

Amazon today announced that more than three million members have joined Prime during the third week of December.

Interstellar was the most popular Prime movie on Christmas day but Hunger Games: Mockingjay Part 1 was the most popular over the entire holiday period. Research firm Millward Brown estimates that Prime members are nearly five times more likely to make a purchase in the same shopping session compared to non-Prime members. The number of customers using Amazon’s mobile app also doubled from 2014’s total, and on Cyber Monday, the retailer said it was processing 33 electronics orders a second from a mobile device.

According to analysts, Amazon had at least 60 million to 80 million Prime members globally in September, months before the start of the holiday season.

This was also the biggest holiday for Amazon Device shipments, with sales twice as high as during the record-setting holiday past year. (NASDAQ:AMZN) had indicated its new Prime membership stood at 10 million new members worldwide without making the actual figure clear.

Amazon shipped to 185 countries this holiday. Among Amazon devices, the all-new Fire tablet was the #1 best-selling, most gifted and most wished-for product across the millions of items available on Amazon.com since its introduction 15 weeks ago.
