The Vice Presidential Debate between Mike Pence and Tim Kaine was watched by an estimated 51 million people, Reuters reported this morning. 

It's in line with the audience that tuned in four years ago and far from a record total.

The Hollywood Reporter, citing preliminary Nielsen and network data from the four main U.S. broadcasters, said the debate scored a 13.2 household rating. That would translate into a total TV audience of around 51 million - about the same figure for the 2012 vice presidential encounter - when the numbers from cable and other channels are included later in the day. 

The debate last week between Donald Trump and Hillary Clinton drew a record audience of 84 million. 

In 2008, the debate between Sarah Palin and Joe Biden was watched by 70 million, while the 2012 Joe Biden-Paul Ryan matchup came in at 51 million viewers.

Final numbers are expected later in the day.

Trump and Clinton are set to square off again on Sunday night at 9:00 ET on Fox News Channel.
