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.[134] 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.[134] 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.[135] 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.[136] 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,[137] though Amazon states:

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.

Twitch started in 2007 as a 24-hour live stream of co-founder Justin Kan’s life (he coined the term “lifecasting”) called Justin.tv, but it became very clear very quickly that live gaming content was more popular than pretty much anything else. In 2011, Twitch spun off gaming-centric channels as Twitch.tv, and it grew exponentially as online games and the technology to broadcast them live on the internet became more widespread and popular.
