It may well be the hottest ticket on the planet.

Super Bowl 50 is still months away, but coveted passes to the game at Levi's Stadium are already being advertised for more than $4,000 on ticket sites. And thanks to the strange alchemy of the industry's secondary marketplace, you're not even buying an actual ticket but rather the promise of a ticket on game day. Good luck.

It turns out Super Bowl tickets are just the tip of a very mysterious iceberg.

"We tell people ticketing is one of the most misunderstood businesses out there," said Jared Smith, president of Ticketmaster North America and the NFL's official ticket partner. "Almost everyone is exposed to the industry at some point, but most have no idea how it all works."

In an effort to shine a little light on this esoteric business, we offer 50 Things About Tickets Most People Don't Know:

1. The break-even point for most events is when 60 to 65 percent of tickets are sold.

2. U2 tickets for $1,200 on StubHub? That's often not what people are buying them for but what sellers are asking (and often won't get).

7. TiqIQ's Jesse Lawrence called Super Bowl 49 "the ticket market's Black Swan" because prices climbed right up to game day, instead of dropping as they often do.

11. When the Los Angeles Dodgers' season tickets went digital, angry fans launched a Facebook campaign: "Bring Back the Paper Ticket."

16. Smith says "bad guys" use technology to virtually game the online buying sites that's "built specifically for cutting in line and buying tickets before fans can buy them."

17. Ticketing is a $5 billion to $6 billion-a-year industry and Smith says "the vast majority of that money is not from Joe Fan reselling on StubHub; it's pros by and large who bought those tickets with the express purpose of using sophisticated algorithms to resell them."

18. Tickets for concerts and theater events generally sell first from the front and back rows, says Goldstar's McCarthy.

19. But he adds "often the best values are in what we in the business call 'the mushy middle.'"
