Amazon employs a multi-level e-commerce strategy. Amazon started by focusing on business-to-consumer relationships between itself and its customers and business-to-business relationships between itself and its suppliers and then moved to facilitate customer-to-customer with the Amazon marketplace which acts as an intermediary to facilitate transactions. The company lets anyone sell nearly anything using its platform. In addition to an affiliate program that lets anyone post-Amazon links and earn a commission on click-through sales, there is now a program which lets those affiliates build entire websites based on Amazon's platform.
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.
The infomercial industry is huge and is worth a staggering $250 billion as of 2015. It all started back in the late 40’s and early 50’s when major sponsors of serial television programs were soap manufacturers (i.e. Proctor & Gamble, Lever Brothers and Colgate-Palmolive), which is how “soap operas” got their name. There is some controversy although the first infomercial is thought to have been for a blender either made by VitaMix or Waring Blenders and aired in 1949 or 1950. Time limits for commercials were imposed by the Federal Communications Commission (FCC) not too long after this which halted the growth of infomercials until 1984 when those limits were removed.
