Katie Couric was in the right place at the right time when she was co host of NBC's "Today." She had the right combination of sweet/perky and gravitas. She stepped in and stabilized a franchise that was out of control The perfect person in the perfect job.
Couric had the desire to do other things. CBS dangled a ton of money in front of her, and I don't blame her for leaving NBC.
Let's examine the post-NBC record.
"CBS Evening News"... bombed.
Daytime talk show... bombed.
Yahoo! global anchor... bombed.
To be fair, much of the CBS failure was on the plate of weak affiliates in major cities. She didn't have much of a lead in, an issue that remains to this day.
Daytime talk shows are tough.
Couric recently blamed management at Yahoo! for her failure there. Her "broadcasts" weren't publicized. Yahoo! didn't give her enough publicity, although she did get some fat paychecks.
Keep your eye on the ball. It all comes down to this: Katie Couric didn't do anything people wanted to watch.
