Children's Miracle Network
 

It shoud be national, with local inserts. We used to do the telethon locally when I worked for a TV station here in Denver, and in later years I managed the TV remote mobile unit that originated the live national show segments from Walt Disney World.

A couple years ago, they dropped the live national segments in favor of pre-produced pieces.

We always liked this charity because all of the money raised stayed right there in your home city (provided there is a Children's Hospital there), and none was used to support huge national organizational bureaucracy.
