What's this kind of "advertising" called?

[asker_of_question]

I heard that movie theaters used to use it to sell more snacks and drinks, by like inserting pictures of popcorn or soda in the middle of a movie for like small fractions of a second, so that you couldn't consciously see it, but you're mind sub-consciously saw it, which made you want it, which increased the theaters sales.<br />
<br />
I think it was made illegal, though, because you were "brainwashing" people to buy things.<br />
<br />
If any of that made sense, lol.<br />
<br />
Thank you.<br />

My guess is "subliminal" advertising.

 

[Butters]

It's a subliminal message.

It is a form of subliminal advertising or persuasion.

Subliminal. And yes, the FCC banned subliminal use of pictures in advertising if used at a rate that the human eye can't detect.

Subliminal advertising - it is illegal today (at least in North America)
