The Sun newspaper uses Poser figures to create one of it's cartoons every day, I've seen poser used on the News on tv, poser has been used a lot in films to previsualise scenes, the movie The One used Poser heavily to set up the most complicated & dangerous stunts. Poser was used during a court case I was in the Jury for to demonstrate to us what might have happened.

So although you don't always see Poser on screen it's been used to help create what you're seeing.
