When it comes to the game and e-sports streaming scene, Twitch is the 800-pound gorilla. But when it comes to online video as a whole, YouTube is the dominant force, which is why the early reports that Google was going to buy Twitch were a little strange.

What Twitch has is a very strong brand, as the site people go to for livestreams of people playing games.
