Charlie Gibson was back on "Good Morning America" today.
But he hasn't quit his day -- rather, evening -- job as anchor of ABC's "World News."
Gibson brought along his fellow evening news anchors from the other networks -- Katie Couric and Brian Williams -- to "GMA's" Times Square studio to announce the joint decision to fight cancer together.
The three networks -- ABC, CBS and NBC -- will each donate one hour of simultaneous, commercial-free primetime to air a fundraising event called "Stand Up to Cancer" Sept. 5, 2008.
The anchors appeared live on "GMA," CBS's "The Early Show," and NBC's "Today Show" to talk about the new initiative.
Cancer research has been placed on the backburner, said Gibson on "GMA," and the networks hope the fundraiser will bring it to the forefront of people's minds.
"The statistics are not good," Gibson said, and the program "is designed to get people's attention focused on cancer research and raise a whole lot of money."
The star-studded special will include live performances from recording artists, and actors and actresses from film and television.
Gibson, Couric and Williams will also report on what's new in cancer research and speak to both patients and scientists.
"We hope to educate you, move and inspire you," said Laura Ziskin, a cancer survivor who will produce the broadcast, in a press release.
