  • Festival season is in full swing.
  • Glastonbury Festival, which typically pours millions of pounds into the UK's economy, ended June 30.
  • But while there are more festivals than ever before, they're not a new phenomenon.

It seems like every other week, there's a new music festival promising to be the greatest weekend ever. In addition to all of these new events popping up around the world, there are the staples like Coachella, Bonnaroo, and Hangout.
