"Search Inside the Book" is a feature which allows customers to search for keywords in the full text of many books in the catalog. The feature started with 120,000 titles (or 33 million pages of text) on October 23, 2003. There are about 300,000 books in the program. Amazon has cooperated with around 130 publishers to allow users to perform these searches.
The Amazon sales rank (ASR) provides an indication of the popularity of a product sold on any Amazon locale. It is a relative indicator of popularity that is updated hourly. Effectively, it is a "best sellers list" for the millions of products stocked by Amazon. While the ASR has no direct effect on the sales of a product, it is used by Amazon to determine which products to include in its bestsellers lists. Products that appear in these lists enjoy additional exposure on the Amazon website and this may lead to an increase in sales. In particular, products that experience large jumps (up or down) in their sales ranks may be included within Amazon's lists of "movers and shakers"; such a listing provides additional exposure that might lead to an increase in sales. For competitive reasons, Amazon does not release actual sales figures to the public. However, Amazon has now begun to release point of sale data via the Nielsen BookScan service to verified authors. While the ASR has been the source of much speculation by publishers, manufacturers, and marketers, Amazon itself does not release the details of its sales rank calculation algorithm. Some companies have analyzed Amazon sales data to generate sales estimates based on the ASR, though Amazon states:
Amazon was founded in 1994 around Bezos’ desire to start an internet-based business, with the goal of selling items online emerging as an early and obvious inroad into the dot-com boom. A former Wall Street worker with electrical engineering and computer science degrees, Bezos zeroed in on books as a viable initial product category for his online store due to the universality of literature, the existing stock of print books, and the relatively low price of each unit. Bezos briefly considered naming his company Relentless.com — an early sign of the man’s tenacious business mindset — but friends and family suggested it was too malevolent sounding. Relentless.com, which Bezos bought roughly 24 years ago, still redirects to Amazon.com. The company now controls almost half of all print book sales in the US.
While Amazon grew in the ‘90s largely thanks to its growing share of the print book market and its dominance of online book sales, it was its early investments in ebooks and e-readers that turned it into a digital publishing and book-selling powerhouse. Amazon began work on its first Kindle e-reader starting in 2004 under codename Fiona, with its internal Lab126 hardware division leading the product development process. The first device was released in November of 2007 and sold for $399. Amazon has since released numerous iterations of the Kindle, and it now dominates the e-reader market after edging out competing products from Barnes & Noble, Kobo, and others.
Twitch is a live streaming platform for video, primarily oriented towards video gaming content. The service was first established as a spin-off of a general-interest streaming service known as Justin.tv. Its prominence was eclipsed by that of Twitch, and Justin.tv was eventually shut down by its parent company in August 2014 in order to focus exclusively on Twitch. Later that month, Twitch was acquired by Amazon for $970 million. Through Twitch, Amazon also owns Curse, Inc., an operator of video gaming communities and a provider of VoIP services for gaming. Since the acquisition, Twitch began to sell games directly through the platform, and began offering special features for Amazon Prime subscribers.
On January 22, 2018, Amazon Go, a store that uses cameras and sensors to detect items that a shopper grabs off shelves and automatically charges a shopper's Amazon account, was opened to the general public in Seattle. Customers scan their Amazon Go app as they enter, and are required to have an Amazon Go app installed on their smartphone and a linked Amazon account to be able to enter. The technology is meant to eliminate the need for checkout lines. Amazon Go was initially opened for Amazon employees in December 2016. In August 2018, the second Amazon Go store opened its doors.
