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.
Amazon has attracted widespread criticism for poor working conditions by both current employees, who refer to themselves as Amazonians, and former employees, as well as the media and politicians. In 2011, it was publicized that at the Breinigsville, Pennsylvania warehouse, workers had to carry out work in 100 °F (38 °C) heat, resulting in employees becoming extremely uncomfortable and suffering from dehydration and collapse. Loading-bay doors were not opened to allow in fresh air, due to the company's concerns over theft. Amazon's initial response was to pay for an ambulance to sit outside on call to cart away overheated employees. The company eventually installed air conditioning at the warehouse.
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.
