In Fahrenheit 451 by Ray Bradbury, television shows are broadcast with parts missing so that viewers can act the scenes out:
She didn't look up from her script again. “Well, this is a play comes on the wall-to-wall circuit in ten minutes. They mailed me my part this morning. I sent in some box-tops. They write the script with one part missing. It's a new idea. The home-maker, that's me, is the missing part. When it comes time for the missing lines, they all look at me out of the three walls and I say the lines: Here, for instance, the man says, 'What do you think of this whole idea, Helen?' And he looks at me sitting here centre stage, see? And I say, I say —” She paused and ran her finger under a line in the script. “ 'I think that's fine!' And then they go on with the play until he says, 'Do you agree to that, Helen!' and I say, 'I sure do!' Isn't that fun, Guy?”
