Doing a final paper and could use some information

I'm in my final year as an economics major and am required to do a final term paper. I was hoping to do something on Esports to see if a company can survive by catering to them and I need some information. Not sure if this is publicly available or if Riot is allowed to answer anything or if they'll even see this post, but I figured I'd ask here just in case.

How much does an event like Worlds cost to run? How much revenue does Worlds usually bring in? How do payouts for the competing teams work? What's the usual viewer count during these big events, and who are the usual sponsors?

I'll probably come up with more, but if any Rioter could answer these, I'd greatly appreciate it.
