Twitter's initial foray into livestreaming eSports must have went well, as it's expanding the range of tournaments it covers in a big way. The social network has reached deals to stream 15-plus ESL One, DreamHack and Intel Extreme Masters tournaments over the course of 2017. ESL will also make its own originals for Twitter, including a half-hour show that covers competition highlights and behind-the-scenes stories. The first tourney to get the treatment is Intel Extreme Masters Katowice, which starts on March 4th.
