To avoid copyright violations, Amazon does not return the computer-readable text of the book. Instead, it returns a picture of the matching page, instructs the web browser to disable printing and puts limits on the number of pages in a book a single user can access. Additionally, customers can purchase online access to some of the same books via the "Amazon Upgrade" program.
Amazon was never going to be able to compete with Google’s YouTube in user-uploaded video content, and it didn’t have the social infrastructure of Facebook to become a destination where people discuss their lives and share videos from around the web. But what Amazon did have was the resources to purchase a company that was poised to outrun both Facebook and YouTube to a new type of business: live-streaming, in particular video games live-streaming. The pioneer of that market was Twitch, which Amazon purchased in 2014 for just shy of $1 billion.
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.
