NEW YORK (TheStreet) -- Amazon (AMZN - Get Report) released an infographic Tuesday to celebrate the ten-year anniversary of launching Prime, and while the infographic fails to include a number on total members, it does reveal some interesting tidbits.

Amazon has long been secretive when it comes to sharing numbers, so it comes as little surprise that the company has not shared how many consumers have signed up for Prime. In its fourth-quarter earnings release, Amazon finally revealed some information, saying that "worldwide paid membership grew 53% last year -- 50% in the U.S. and even a bit faster outside the U.S." The company has also noted that the number of Prime users is in the tens of millions.

Despite the secrecy around the number analysts and investors are pining for, Amazon has shed some light on the habits and activities of its Prime members.

The infographic Amazon released Tuesday shows that the fastest delivery in Manhattan on Prime Now, an app Amazon is testing for instant delivery, was 23 minutes for an Easy-Bake Ultimate Oven. Since Prime Now is often compared to Google (GOOG - Get Report) Express or Instacart, one might have thought the fastest delivery would have been for a more mundane item like a bag of chips or plates.

But the fact that Prime Now members ordered an Easy-Bake Oven means that consumers are ordering a broad range of products from the instant delivery app.

Here's the full infographic:

It's also interesting to see how much Amazon offers its Prime members -- videos, music, photo storage, and library. Amazon is really stocking up Prime, and it seems to be worth it.

"Prime members are buying more," Amazon CFO Tom Szkutak said in the fourth-quarter earnings call. "It's more convenient. They are getting their physical product to them faster versus being not a Prime member. Certainly as you think about customers who are not Prime that become Prime, we see a very sizable step up their purchasing patterns. And so the customers are certainly buying a lot more from us."

When asked why Amazon does not reveal the number of Prime members, Amazon spokesperson Julie Law responded, "We don't release the number of Prime members because it is highly competitive and frankly, we believe our members care more that we are adding value to their membership, so that Prime is something they can use every day. We don't have plans to release them in the future."
