Early overnight Nielsen ratings suggest that Thursday’s Republican debate was not just the most-watched primary debate in history — it may have been twice as big as the previous record-holder. The debate on Fox News had a 16.0 household rating between 9 p.m. and 11 p.m., according to Nielsen. Translation: 16% of United States homes with TV sets tuned in. Fox News usually has 1% or 2% of the household audience. For the sake of comparison, the highest-rated Republican primary debates in 2011 and 2012 were watched by approximately 5% of households.
Last night may have been the most-watched Fox News telecast ever.
