Propaganda?

How did you arrive at this proposal? Is the Mona Lisa propaganda because she isn't holding a branded flask with snake oil?

GP responded to a comment about broadcasts, not paintings. I think the GP wasn't so far off. If you are not selling products you are still presenting viewpoints, experiences, and ideas.

I remember seeing images of paintings on television so I don't agree that it would somehow be impossible.

What definition of propaganda are you using here?
