US cable news viewership trends

In September, Fox News remained the most-watched cable news network in total viewers despite experiencing significant declines. During primetime, the network averaged approximately 1.72 million viewers, representing a 32% decrease from the previous year. Conversely, MSNBC showed growth in several categories, including a 3.6% increase in primetime viewership and a 16% increase in the 25-54 demographic. CNN reported mixed results with a slight decrease in primetime viewership but growth in the 25-54 demographic.

By October, preliminary data indicated a continued dramatic decline for Fox News, which was on track for its lowest-rated month since December 2023. The network averaged approximately 1.1 million total viewers, with a 32% decrease in the 25-54 age demographic marking its lowest ratings in 25 years. While Fox News maintained higher viewership than other cable networks, liberal-leaning networks such as MSNBC and CNN reported modest viewership increases during this period.

As midterm elections approach, Fox News continues to face a substantial decline. Nielsen data indicates the network is on track for its weakest October in years, with total viewership projected to average 1.1 million, a 27% decrease compared to the same period in 2025. The decline is most pronounced in the 25-54 age demographic, which is seeing its lowest levels in 25 years, down between 32% and 36% year-over-year. Analysts suggest this slump may correlate with declining approval ratings for President Donald Trump and waning enthusiasm among the Republican base, noting that the network has also faced criticism from Trump regarding its coverage of certain Democratic candidates.
