I agree with Aaa

I think in the English language we have come to relate the word "stuff" with tangible personal property. Because you are trying to relate it with television programming instead, perhaps it is giving you a 'bad English' reflex?

I think I can actually answer this. I am a vocal "Impressionist" vs. an "Impersonator". Impression means to take on only a single aspect of the original while Impersonation means to replicate the original in its entirety. In entertainment, Rich Little would be an "Impressionist". Shawn Klush would be an Elvis "Impersonator", etc.
