Over half a million more viewers Friday night tuned to Fox News Channel over CNN as news broke that the manhunt for the second suspect in the Boston Marathon bombing was over. In the 7 PM ET hour, Fox News was number one among cable news networks with 5.748 million viewers compared to CNN’s 5.195 million. However, the Jeff Zucker-run network bested the News Corp-owned FNC in the key adults 25-54 demographic during the crucial hour Friday; CNN had 2.322 million in the demo to FNC’s 1.574 million. MSNBC was third in viewership and the demo with 1.429 million watching and 459,000 in 25-54. Over the total day, the result in the demo and viewership was the best CNN has done for a non-political event since the 2003 launch of the Iraq War. With the exception of Election Day last year, FNC had its highest rate viewership in both total day and primetime since 2003 also.
