When Tucker Carlson was getting ready to take over as Bill O’Reilly’s replacement at Fox News this spring, he said network boss and 21st Century Fox Executive Chairman Rupert Murdoch told him, “relax and enjoy yourself.” 
  
 Relaxation and enjoyment may have been in short supply inside the halls of Fox News over the past year. Turbulence from sexual-harassment scandals led to the exits of the network’s two top executives, Roger Ailes and Bill Shine, and its biggest star, Mr. O’Reilly.

A:
Despite sexual-harassment scandals that prompted marquee-name resignations, Fox News is still on top. Rupert Murdoch's network clinched the most prime-time viewers among cable news networks, reports the Wall Street Journal, and even increased its hold among the much-desired demographic of 25- to 45-year-olds in the latest Nielsen ratings ending in June. The score surprised some media observers who expected Fox to take a hit after losing star host Bill O'Reilly, who was replaced by Tucker Carlson. While his audience is smaller, Carlson is beating O'Reilly in the coveted 25-to-54 group, and the network gained 21% overall in that age group over last year. The Five round-table show saw a rise after replacing The Kelly File, following host Megyn Kelly's jump to NBC. (Adweek has a scorecard by time slot.) But it wasn't all bad news for the runners up: All three networks are clocking far more viewers than before the presidential election, though Fox has watched its lead slip since November. Left-leaning MSNBC is closing in with the biggest ratings growth—72% among 25- to 54-year-olds over the past year—thanks to Rachel Maddow's show, which is tops among that demographic. Last Word with Lawrence O’Donnell saw a 97% boost among that same group, though it still lags behind Sean Hannity's show on Fox News, which gained 31%. Overall, Fox News racked up 472,000 prime-time viewers, with 389,000 for MSNBC, and 370,000 for CNN. Fox News co-President Jack Abernethy tells the Journal that 2017 has been "a great year by virtually all measures." (President Trump, for his part, is no fan of CNN.)
