First on TVNewser: Paula Zahn has resigned from CNN. Zahn hosted CNN's 8pm ET program, Paula Zahn Now.

The departure comes just one day after Campbell Brown signed on with CNN. TVNewser joined a conference call around this time yesterday, in which CNN/U.S. president Jon Klein introduced Brown as his network's newest on-air hire. Klein promised an announcement about Brown's primetime program would be made "over the next several days."

Zahn joined CNN in 2001. Her first day on the air was September 11, co-anchoring coverage of the 9/11 attacks with another new hire at the time, Aaron Brown. Later that fall, Zahn began hosting American Morning. From 1999-2001 Zahn anchored a primetime show on Fox News Channel called "The Edge."

To All,

It is with mixed emotions that I announce my departure from CNN, effective Thursday, August 2nd. I'd like to take this opportunity to express my tremendous respect for my good friends and colleagues, their talent and high standards.

It's been an extraordinary journey since my first day on the job, September 11th, 2001. During my 6 years with CNN, we've covered the war in Iraq, the devastation of Hurricane Katrina, the death of a Pope and the massacre at Virginia Tech. I am enormously proud of the work we've done covering these stories as a team.

Now is the right time for CNN and me to move ahead on different paths. I wish good luck and success to everyone I was fortunate to work with. And for the first time in 30 years, I plan to take a break between jobs and catch my breath before I take on my next role.

- Paula
