Amazon's state sales tax collection policy has changed over the years since it did not collect any sales taxes in its early years. In the U.S., state and local sales taxes are levied by state and local governments, not at the federal level. In most countries where Amazon operates, a sales tax or value added tax is uniform throughout the country, and Amazon is obliged to collect it from all customers. Proponents of forcing Amazon.com to collect sales tax—at least in states where it maintains a physical presence—argue the corporation wields an anti-competitive advantage over storefront businesses forced to collect sales tax.
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.
