Every great investigator tells a story about the one that got away.

For many, this development raises a number of questions. Are these really athletes? (Hint: the U.S. government thinks so.) Why was Amazon willing to pay almost a billion dollars for Twitch.tv? And, well, just how does professional gaming work?

You’re also in luck, because I’ve broken them all down for you in a brief and handy-dandy article called (descriptively enough) …

What’s the deal with those laundry symbols, and how do I tell them apart?
