Not completely true. Everyone wanting to want to watch it at the same time causes issues. Other videos you can distribute the video to caches ahead of time, so the burden on the outgoing connection is less.
Are you describing a problem between live streaming and pre-recorded video? How does Twitch handle their load? How many more people are watching the average football game vs watched "Twitch Plays Pokemon" at its peak?
Edit: TPP had 60,000-70,000 simultaneous viewers on average, with a peak of 120,000.[1] In 2014, each NFL game had about 17.6 million viewers.[2] So an order of magnitude increase. How well does live streaming video scale horizontally?
stephengillie, "twitch plays pokemon" maxed out at 121,000 concurrent (according to Twitch) viewers, last years Super Bowl maxed out at 120,800,000 viewers. So yes, I would say it is a considerably different scale.
