When you think of user-made online video, I bet the site that instantly springs to mind is YouTube. In fact, if I asked you to name another similar site, you might draw a blank. That's how much YouTube dominates the market.
Well, at least that's how much it dominates part of the user-video market. YouTube's live streaming service never really took off the way it hoped.
That's why it's rumored to be in talks to buy Twitch. This live-streaming video site claims 45 million monthly users with 1 million people uploading videos each month.
In March, Twitch hit 1.35 percent of American Internet traffic. That would be a big addition to YouTube's 13.2 percent.
