As part of the changes, many of Fox News Channel's best known daytime anchors will find themselves leading new time slots and shows. Harris Faulkner, who hosts two hours from noon to 2 p.m.,  will now anchor the 11 a.m. slot as well as her noon program, "Outnumbered." Bill Hemmer, who took over a 3 p.m. slot previously anchored by Shepard Smith, will return to co-anchoring the network's first two hours of news programming at 9 a.m. – and will be paired with Dana Perino. John Roberts and Sandra Smith will co-anchor two hours in the early afternoon. And Martha MacCallum will move to 3 p.m., the hour previously led by Hemmer.

A rotating group of Fox News opinion hosts will take over the 7 p.m. hour, which will now be titled "Fox News Primetime." While TV networks and advertisers typically consider primetime to take place between 8 p.m. and 11 p.m., the cable-news networks view the 7 p.m. hour to be among their best-watched programs and consider that hour to be part of their most popular program blocks. A permanent host is expected to be named at a later date. MSNBC last year placed Joy Reid, an opinion host with a penchant for colorful turns of phrase, in its 7 p..m. hour.Brian Kilmeade, one of the co-hosts of "Fox & Friends" will fill the hour in its first week.
