Kelly beat out Fox's longstanding ratings-topper, Bill O'Reilly, for the prized 25-54 demographic in August, averaging 566,000 daily viewers -- a 41 percent jump from her ratings in that category the previous month. Kelly's ratings win comes despite her 10-day vacation.
However, "The O'Reilly Factor" remained the top-watched news program in total viewership, outpacing Kelly's total audience by approximately 250,000 viewers.
Fox is still the top-rated news channel, and is home to 14 of the top 20 most-watched news programs. The network hosted the GOP presidential debate on August 6 -- earning a record 24 million viewers -- and bested not only its news competitors, but also other ad-funded cable channels like ESPN. CNN came in second in viewership, with MSNBC coming in third.
In other ratings news, NBC's "Meet The Press" saw its highest ratings in 18 months in August, with 3.6 million viewers tuning in to watch a one-on-one interview with Trump. At CNN, Anderson Cooper's "Anderson Cooper 360°" was the top-watched non-Fox news program, coming in at number 11. CNN is also expecting record viewership in September, with the upcoming GOP debate on Sept. 16.
While August's news was dominated by the first GOP debate, other stories gained a significant amount of coverage towards the end of the month, like the 10 year anniversary of Hurricane Katrina, the stock market plunge and the recent shooting in Virginia that left two journalist dead.
