You might not want to count on revisiting that favorite League of Legends match or Playdate stream in a few years' time -- not as long as it's hosted on Twitch, anyway. The game video service has implemented new policies that delete the full copies of past broadcasts after a fixed period. You'll keep them for two weeks if you're a free user, and 60 days if you're either a Turbo subscriber or one of Twitch's partners. Only highlights (up to two hours each) will stick around indefinitely. Your clips are safe for the three weeks following this post, but you'll want to quickly move them elsewhere if you're bent on keeping them for posterity. The site is also starting to mute audio (in recordings, not during live streams) that you don't have the rights to play, so you may not want to blast tunes in between rounds -- it's using the same tech that YouTube used before it launched Content ID, which adds a little more weight to those Google acquisition rumors.
