Twitch started in 2007 as a 24-hour live stream of co-founder Justin Kan’s life (he coined the term “lifecasting”) called Justin.tv, but it became very clear very quickly that live gaming content was more popular than pretty much anything else. In 2011, Twitch spun off gaming-centric channels as Twitch.tv, and it grew exponentially as online games and the technology to broadcast them live on the internet became more widespread and popular.
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.
