Wanna feel old?

Amazon Prime, the company’s premium subscription service that offers customers free two-day shipping on millions of products, is now a decade old. Amazon debuted the service in February of 2005.

The company is celebrating the birthday by releasing some stats about the service. Of course, Amazon is still tight-lipped on the most important stat – exactly how many total members Prime has.

Amazon does tell us that there are over 20 million items available for Prime shipping, and that 221 different types of toothbrushes are delivered same-day. Also, Prime members could order 856 items every day for the rest of their lives a still not order every item available on Prime.

According to Amazon, the most-watched program on Prime Instant Video is Downton Abbey.

But the only stat that Amazon leaves purposefully vague is the total user base. Amazon will only say that Prime has “tens of millions of members”.

Amazon recently revealed that Prime membership grew 53% last year (50% in the US), despite the fact the company jacked up the price in March of 2014.

In a recent interview with the Wall Street Journal, Amazon’s VP of Prime Greg Greely refused to reveal more specific user figures for Prime, saying only that,

“We’re not letting out the numbers. Lots of competitors would love to know that. It’s continuing to be a very important part of our business.”

Amazon finally turned a profit last quarter after multiple quarters of loss. It’s safe to say that Prime is an integral part of the business. Amazon doesn’t really make money on the Prime subscriptions itself – but Amazon has confirmed that Prime members spend way more than non-Prime members on the site.
