Republican 2016 U.S. presidential candidate businessman Donald Trump (L) talks with fellow candidate and former Governor of Florida Jeb Bush during a commercial break at the first official Republican presidential candidates debate of the 2016 U.S. presidential campaign in Cleveland, Ohio, August 6, 2015.
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.
