After all, that was the only benefit to the retailer's loyalty program when it started in 2005 and cost $79 per year.

But Prime has changed a lot since then, and it's no longer just about the free shipping.

A membership also now costs $99 per year.

Here's an overview of everything you now get as a member of Amazon Prime.

Access to Prime Video, a growing catalog of streaming movies and TV shows.

Prime subscribers can stream content from Prime Video, Amazon's Netflix-like streaming service. It's mostly older shows and movies, but it has a mix of newer programming, original content, and even a back catalog of HBO shows. Noteworthy original shows that you can't stream anywhere else include "Transparent," "The Man in the High Castle," and "Mozart in the Jungle." You also have access to movies and TV shows.

You can also add subscriptions to Showtime, Starz, and more.

Prime subscribers can add additional video services to their Prime accounts. They're not free, but some are discounted. A subscription to Showtime's standalone service, for example, is regularly $10.99 per month, but Amazon discounts it to $8.99.

Access to a streaming music catalog.

Amazon Prime also gives you access to a streaming music catalog. It doesn't have the selection that Spotify or Apple Music has, but it's a great perk that's included with Prime.

Unlimited photo storage.

Access to the Kindle Owners' Lending Library and Kindle First.

The library allows Kindle owners to borrow one book per month for free. Kindle First gives Prime members early access to books before they're published, and allows members to download one title per month for free.

Early access to some deals and promotions, as well as discounts on other products.

Access to Amazon Elements.

Prime members get access to Amazon Elements, the company's line of environmentally friendly household and baby goods. Currently, however, baby wipes are the only Elements product, as the company stopped selling its diapers last year.

Access to Prime Pantry.

Prime Pantry is a grocery and household product-delivery service, though it works in a unique way: You fill a box with various products, and shipping is a flat $5.99 per box.

Free same-day shipping — in eligible areas.

This is the perk that started it all: free two-day shipping on millions of Amazon items.
