n September 5, Katie Couric will become the first woman to be the sole anchor on a network newscast. CBS (cbs.com) took Couric away from NBC with a four year, $60-million contract earlier this year.

Closer to September, CBS will promote Couric through its network siblings which include CBS outdoor and CBS Radio. As part of that initiative, Couric's face will appear on the front of New York buses for the month of September. And the on-air promotion has already begun. Current evening news anchor Bob Schieffer has been appearing in ads running on CBS to explain the changes and his shift back to Washington.

The network is also giving Couric a daily blog, which is aimed at engaging viewers even further. Also in the afternoon each day, Couric will also appear in a video segment to talk about what's going on in the world that day, the video clip of which will be available on CBSNews.com... more
