Costolo is also envisioning a "DVR mode" that lets people keep up with the discussion around live events — like the Mad Men season finale, for example — that they might be watching on a delay. Overall, the CEO is looking to make it easier to cut through the noise of Twitter during events without losing the feel of a live, free-flowing discussion. "That ability to track and monitor the moments within an event, either as they happen or to catch up with them, is something we want to enhance," said Costolo. "We want to make that experience even better, curating the moments within the event, the media from it, and making it that much easier to navigate."

Costolo referred to Twitter's previous attempts at distilling the massive volume of information that comes out of major events for its users — he specifically cited the company's 2012 Olympics spotlight site as an effort that ultimately didn't work the way he wanted it to. "The amazing thing about that was that you lost the roar of the crowd," he said — it sounds like the approach was a bit too curated for Costolo's tastes. While these features are still in the testing phase, it wouldn't surprise us to see them roll out before a high-profile event — like next year's Super Bowl.
