Worlds 2015 Advertising @RITO

I've watched several League tournies so far and one thing I've noticed is that there were no advertisements inbetween matches. I was wondering if this was a deliberate choice by Riot to leave out advertising for the players. I found it odd that an event that gathered millions of players to watch the same thing had nothing going on inbetween games. Personally I would have preferred to see some advertisements inbetween games rather than staring at the audience members moving around to go to the bathroom.

What does the community think of advertisements on league?
