Amazon derives many of its sales (around 40% in 2008) from third-party sellers who sell products on Amazon. Associates receive a commission for referring customers to Amazon by placing links to Amazon on their websites if the referral results in a sale. Worldwide, Amazon has "over 900,000 members" in its affiliate programs. In the middle of 2014, the Amazon Affiliate Program is used by 1.2% of all websites and it is the second most popular advertising network after Google Ads. It is frequently used by websites and non-profits to provide a way for supporters to earn them a commission. Amazon reported over 1.3 million sellers sold products through Amazon's websites in 2007. Unlike eBay, Amazon sellers do not have to maintain separate payment accounts; all payments are handled by Amazon.
The main con is obviously the cold, crowds, and chaos. But just because Black Friday traditionally means in-store shopping, doesn't mean that many retailers won't offer sales online. Last year, online sales hit 19.62 billion over the five-day period from Thanksgiving through Cyber Monday. So if you don't want to wake up in the middle of the night to battle crowds and wait in long lines, check with your favorite stores to see if you can do it all from the comfort of your home.
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.
