Katie Couric‘s ascension to the CBS Evening News anchor chair will be “a dramatic change” for the network, Matea Gold says.

“Her hiring represents a major coup for CBS Corp. President Leslie Moonves, who has been courting Couric for the last year and has advocated shaking up the evening news format.”

More: “The program is not expected to change dramatically; rather, the broadcast probably will be adjusted to showcase Couric’s personable nature, much as Schieffer has loosened the format by chatting with correspondents at the end of segments.”
