Inside Katie Couric’s Disastrous Yahoo Experiment. “She moved to online with great fanfare, but quickly became the forgotten woman of journalism. How did it all go so wrong for Katie Couric at Yahoo?”

Earlier this month—nine months after resigning from the company—Couric summed up her four years at Yahoo on a Recode Decode podcast.

“I wouldn’t say it was an unhappy marriage, but it certainly was not fulfilling for me,’’ she said. “I had all this great content, I was getting big interviews—and it was sort of like a tree falling in the forest.”

Part of the problem, according the Post’s Oli Coleman, was that Couric was fighting for traffic with one hand tied behind her back, as Yahoo’s CEO, Marissa Mayer, had set up Yahoo News to be “a slave to an algorithm: If you read Kardashian stories, you’d be fed more pop culture; if you read Tom Brady stories, you’d get more NFL news.”

Unfortunately for Couric, the Yahoo algorithm bestowed no preferential status on Yahoo content. If Couric had assumed that at least regular Yahoo users—and there were of course millions of them at the service’s height—were automatically going to be seeing more of her, she was wrong, as users were much more likely to be pointed to non-Yahoo sites based on their browsing history.

That’s the kind of thing a more internet-savvy TV star should look into before making a career-changing move into a new medium.
