When it comes to eSports this site has mainly been covering the games themselves, Quake being at the forefront. But eSports is becoming a lot more than a "game" someone is competing in, be it offline or online, at an event or tournament. Stepping back and looking at eSports you will notice there is a lot more to it and most notably it's becoming a business.
Georgetown University School of Continuing Studies in Washington, D.C. The panel was moderated by Sean "Day[9]" Plott with special guest panelists Chris Radtke (Ziff Davis), Ben Goldhaber (Twitch) and Rod "Slasher" Breslau
The panel is divided in 5 parts on YouTube and is about a 100 minutes long altogether. Some interesting points being, speakers mentioning Quake as their eSport game and furthermore "Slasher" mentioning ESReality as the start of his career as a journalist.

Business of eSports Panel w/ Day 9

Part 1 - Topic: Business model

Even though being a year and a half old now, still some valuable information was presented at the panel and I strongly suggest it to anyone, even remotely interested in this side of eSports to, well, watch it.
