The first Republican presidential debate is shaping up to be the most-watched primary debate in history.
The New York Daily News reports that early Nielsen numbers reveal that the debate earned a 16.0 or a total of 16% of U.S. homes with a television were tuned into the debate on Fox News.
According to the newspaper, CNN reported that the highest-rated Republican primary debates in 2011 and 2012 were both watched by 5% of U.S. homes with a TV.
Additionally, a Fox News representative told the paper that so many people tried to watch the debate online that the “overwhelming demand caused server issues in the debate live stream.”
Nielsen is expected to release more viewership information on Friday afternoon.
CNN and CNBC will air the next Republican presidential primary debates on September 16 and October 28, respectively.
