LOS ANGELES (AP) -- Adam Sandler, Seth Rogen and Neil Diamond were among the more than 100 celebrities to appear on all four broadcast networks for the "Stand Up To Cancer" telethon.

Ryan Seacrest, Jay Leno and George Clooney also showed up to help raise money at the hourlong fundraiser that was simulcast commercial-free Friday night by ABC, CBS, Fox, NBC, a number of cable channels and the Armed Forces Network.

The event was hosted by news anchors Diane Sawyer, Brian Williams and Katie Couric and produced by Film and TV producer Laura Ziskin, a cancer survivor.

Donations to the telecast will go to fund innovative cancer research. The first telethon, in 2008, helped raise more than $100 million. Numbers for the 2010 telethon were not immediately available.
