Audible.com is a seller and producer of spoken audio entertainment, information and educational programming on the Internet. Audible sells digital audiobooks, radio and TV programs and audio versions of magazines and newspapers. Through its production arm, Audible Studios, Audible has also become the world's largest producer of downloadable audiobooks.

That same year, the company launched Dash buttons for instant reordering of products like laundry detergent, and it’s more recently been investing in new services that let package-carrying couriers unlock the truck of your car and even your front door. Most recently, Amazon has signaled an intention to disrupt health care by purchasing online pharmaceutical startup PillPack. All of this has helped Amazon grow its North American retail operation at an unbelievable pace; annual sales for the division more than doubled from $50.8 billion in 2014 to $106.1 billion last year.
Cyber Monday generally means more retailer-wide discounts, rather than product-specific ones that pop up on Black Friday, says Novickis.

Shelfari was a social cataloging website for books. Shelfari users built virtual bookshelves of the titles which they owned or had read and they could rate, review, tag and discuss their books. Users could also create groups that other members could join, create discussions and talk about books, or other topics. Recommendations could be sent to friends on the site for what books to read. Amazon bought the company in August 2008. Shelfari continued to function as an independent book social network within the Amazon until January 2016, when Amazon announced that it would be merging Shelfari with Goodreads and closing down Shelfari.
In 2015, Amazon surpassed Walmart as the most valuable retailer in the United States by market capitalization. Amazon is the third most valuable public company in the United States (behind Apple and Microsoft), the largest Internet company by revenue in the world, and after Walmart, the second largest employer in the United States. In 2017, Amazon acquired Whole Foods Market for $13.4 billion, which vastly increased Amazon's presence as a brick-and-mortar retailer. The acquisition was interpreted by some as a direct attempt to challenge Walmart's traditional retail stores.
