Facebook

Same as the last two events, Facebook Live will leverage its deal with ABC News to broadcast the debate without commercials. As before, the social network will add in commentary from viewers as well as additional features not available to those watching on the TV. In addition, plenty of other outfits will use Facebook Live to stream their own versions of the debate, including Buzzfeed, CNBC and the New York Times.

Twitter

As part of the company's live video push, Twitter will, once again stream Bloomberg's feed of the debate. You'll also be able to enjoy the newswire's on-air analysis paired with Twitter's world-famous well-considered and thoughtful one-eyed invective.

YouTube

When it comes to high profile events that need streaming video, YouTube's uniquely-placed to throw its considerable weight around. The site will serve streams of the debate from NBC, CBS, Fox, PBS, C-Span, the Washington Post, the New York Times, Univision and Telemundo. In addition, YouTube creators The Young Turks and Complex News will be offering a different sort of commentary experience live from their smartphones.

On TV

If you're not yet wedded to the notion of cord cutting, that's okay, because you're gonna be looked after with the traditional broadcasters. The debate will be shown on ABC, NBC, CBS, Fox, MSNBC, CNN, C-Span, PBS, Telemundo, Univision and Fox News.
