The obvious one would be Television. It's as phony as all get-up.
I once went to see a show made (once was enough). It was supposed to be a comedy and they recorded lots of laughter (we laughed on cue) before the show started. That was so they could feed it into the gaps where there was no laughter.
But when the show started the impromptu humour, on camera, between members of the cast was pretty good. Then a woman missed her cue and they had to start all over again. Same "impromptu" remarks, all carefully scripted.
I wasn't too surprised when the show was canned during its first season.
