If you're a die-hard Doctor Who fan, Twitch is about to make your summer. The livestreaming service is teaming with BBC Studios on a seven-week Doctor Who viewing event on May 29th that will show more than 500 classic episodes of the Time Lord's adventures, dating all the way back to the first black-and-white season in 1963. It's not the usual marathon -- the company will air a batch of episodes every day on its TwitchPresents channel starting at 2PM Eastern. The Yogscast team will produce shows to introduce each Doctor, so you'll hopefully know the differences between Tom Baker and Sylvester McCoy (hint: there are many) by the time all is said and done.
