I would just like to say, what a staggering accomplishment have 69,000 viewers is! Well done. However, this is not a north american esports record. Over 100,000 viewers simultaniously tuned in to watch MLG Dalls in March. They have not released the figures yet for MLG Columbus but I would expect them to eclipse their own mark. A week after MLG Dallas the TeamLiquid.com website had over 80,000 viewers watching their TSL event.
Again, not to detract from an awesome accomplishment for League of Legends, I just want to make sure the credit sits where it is due.
