Fox News Channel celebrated its 17th birthday last night with the unveiling of its new expanded primetime lineup and a bigger piece of cake than its cable news rivals combined. However, that slice was a little smaller than Fox News had last Monday. While up 1% to 2.027 million from its September 30 overall 7-11 PM viewership, the revamped Fox News was down 15% to 329,000 among adults 24-54 from the big news night last week that marked the beginning of the government shutdown. That being said, with the debut of The Kelly File at 9 PM, Hannity moving to 10 PM, On The Record With Greta Van Susteren now at 7 PM and The O’Reilly Factor staying at 8 PM, FNC beat the 1.009 million total viewers and 314,000 in the demo MSNBC drew Monday and the 516,000 total viewers and 144,000 25-54s that CNN drew. Comparing cable news networks in the 8-11 PM block, Fox News was also typically No. 1 with 2.059 million overall viewers and 318,547 in the demo. Tied with last week’s overall viewership, FNC was down among adults 25-54 from September 30’s 393,000 in the demo. MSNBC had 946,861 total viewers between 8-11 PM last night with 292,874 in the demo, while CNN drew 519,786 total viewers and 145,193 among the 25-54s. Compared to the recently ended 3Q 2013, the new expanded primetime lineup bumped up 6% in the 25-54 demo to and 15% in overall viewers.
