The running joke about a Ronda Rousey fight is that you can fit the whole thing into a 15-second Instagram video, if not a 6-second Vine -- she's so good that her opponents usually crumble in seconds. You may not see many of those bite-sized clips from her title bout this weekend, though. In a first, UFC is discouraging the press (not just the general public) from sharing unauthorized footage of the fight on the internet, whether it's a GIF animation or a looping video. There's no official explanation, but it's easy to see the concern: the league is worried that you'll skip that pay-per-view purchase knowing that a fan site could recap everything in a tweet.
