In November 2013, Amazon.com announced a partnership with the United States Postal Service to begin delivering orders on Sundays. The service, included in Amazon's standard shipping rates, initiated in metropolitan areas of Los Angeles and New York due to the high-volume and inability to deliver timely, with plans to expand into Dallas, Houston, New Orleans and Phoenix by 2014.
Prime started as a two-day shipping membership for devoted Amazon shoppers, and it didn’t add any additional benefits until 2011. However, since then, Prime has grown into a subscription service with more than 100 million paid users worldwide, while the service itself has evolved to include additional perks over the years, including a Prime credit card now with 5 percent cash back. (Amazon also operates Amazon Pay for purchasing online goods elsewhere with your Amazon account, and the Amazon Cash service for translating cash into store credit using a barcode, although neither are restricted to Prime users.)
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.
