It’s been a rollicking week for observers of the bicoastal political-media revolving door. Most notable was a trio of cable news programming announcements, with Fox News adding Jesse Watters to the 7 pm hour; CNN poaching Audie Cornish from NPR to helm a new show on CNN+, its forthcoming streaming platform; and MSNBC hiring Symone Sanders, the talented Bernie-and-Biden campaign pro, to host a weekend program on the network’s linear channel and another show for its digital outpost on Peacock. As my colleague Dylan Byers wrote yesterday, each move portends how these networks are incrementally pivoting talent in anticipation of a world where the traditional cable business is inevitably going away.
