Katie Couric says that when she joined CBS News as Anchor, she moved too fast in trying to shake things up at the network.

“[CBS President] Les Moonves brought me into CBS to shake things up,” she said during an interview at Fortune’s Most Powerful Women Summit on Monday evening. “I probably should have done that at a slower pace.”

“It’s enough of a shock to see a woman on the evening news, and then to have someone who was changing formats, it was too much too soon,” she said. Furthermore, she said she should have played the game more while at CBS, and “been more political and sucked up to the right people.”
