The last time an event like this happened was after Sept. 11, 2001.

The three major networks - CBS, NBC and ABC - will all team up on Sept. 5, 2008, to raise money for cancer research and patient advocacy. All three nets will simultaneously broadcast an hour of commercial-free programming featuring stars and recording artists.

All three network anchors will formally announce this collaboration on their respective morning shows: Katie Couric on the CBS Early Show, Brian Williams on Today and Charles Gibson on Good Morning America.

The event is sponsoring Stand Up To Cancer, a cancer fundraising drive.

Personally, I cannot wait for this event. It will be monumental - three major competitors are collaborating to fight a disease affecting millions. And there’s no doubt it can make a difference.

So watch. You have no excuse not to - you have more than three months to schedule.
