Can I watch the presidential debate online? Here's what to know and where to go

Impact

The first presidential debate on Sept. 26 was the most-watched debate in U.S. history, with 84 million viewers, according to Nielsen. The second debate, held Oct. 9, wasn't far behind, with 66.5 million viewers.  

But that's just counting television viewers. Social media and online news has dominated the 2016 election. Voters no longer have to rely on traditional media to stay informed.

During the first debate between Republican candidate Donald Trump and Democratic candidate Hillary Clinton in September, there were 17.1 million Twitter interactions from 2.7 million people in the United States, according to Nielsen.

And during the second debate, 18.2 million people in the U.S. had 62 million social media interactions across Facebook and Twitter, Nielsen reported.
