We all love Amazon Prime, but we didn't think this many people loved the service this much.

The online retailer has been pretty quiet about just how many of their users actually pay for Prime, the company's annual subscription-based service, but Amazon have finally shared the number—and it's massive.

In the company's annual shareholders letter, Amazon's CEO Jeff Bezos shared that just 13 years after creating the popular service, they finally were able to surpass the 100 million mark in paid Prime members.

With such an amazing feat, Bezos shared that 2017 saw Amazon Prime crossing off some pretty huge milestones, saying: “In 2017, Amazon shipped more than five billion items with Prime worldwide, and more new members joined Prime than in any previous year—both worldwide and in the U.S.”

Bezos also shared some information regarding Amazon Music, saying:

“Amazon Music continues to grow fast and now has tens of millions of paid customers. Amazon Music Unlimited, our on-demand, ad-free offering, expanded to more than 30 new countries in 2017, and membership has more than doubled over the past six months.”

In addition to the growing count of subscribers in both Prime subscribers and Music, the company also shared that 2017 was the best year for their hardware sales. According to Bezos, customers of the company have bought “tens of millions” of popular devices like Echo devices and the Fire TV Stick with Alexa. 

These are pretty impressive achievements, if we do say so ourselves.
