More than 80 million people viewed Monday's first presidential debate between Hillary Clinton and Donald Trump, making it the most watched debate ever, according to Nielsen research.
The previous record was the only debate between Republican Ronald Reagan and President Jimmy Carter in 1980, which drew 80 million in an era with far few channels and no Internet. In 2012, the first debate between President Obama and Mitt Romney in 2012 drew 67 million viewers.
The 80 million number doesn't include numerous streaming options made available.
