Amazon's home page provides three methods to start finding and buying items. The front page itself shows off featured items, and once the site starts learning your tastes, it will display products based on your history. To find a specific item, type in the search bar at the top of the page. Press "Enter" to search the entire catalog, or select from the drop-down menu set automatically to "All" to search a specific category, which also enables the "Refine" capability for more specific results. If you'd rather just window shop, click "Shop by Department," to pick a section to browse.
Shortly after the first Kindle launched, Amazon premiered its Kindle Direct Publishing platform to let authors self-publish and sell books on Amazon. Two years later, the company launched its own suite of professional imprints called Amazon Publishing. Amazon now oversees tens of millions of self-published works on its platform and nearly two dozen imprints. In 2017, Amazon had more than 83 percent of all US ebook sales.
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.
