When creators of television programs want the 'powers that be' to put their shows on the air, they usually have a meeting of some sort, 'pitch' their show.  After the 'pitch', the 'powers that be' watch a clip/segment/episode of said show and decide if they want to produce the show.

When Jim Henson and his crew wanted to 'pitch' The Muppet Show, they let one of the Muppets do the 'pitch' for them.
