Not only do most people believe with all their hearts that flashing lights on the face of the TV are actual people going through the actual situations presented, there's an entire culture of entertainment and thoughtful criticism that regards this as more important than the reality which manifests the TV unit.
By the measure of TV, the Turing Test was passed by world-wide consensus the 1960s.
What's funny (strange) about TV's grip on our minds is that you'll rarely, if ever, meet anyone who if you ask about how those people live inside the TV will take the question seriously-- they'll just listen with perplexed expression-- but you can change the subject immediately to a show and they will regard mere hearsay about it as a matter of worldly reality, without question, and if they personally have seen the show, they will regard its characters and situations as social fact with all seriousness, no matter how contrived or absurd, and without concern about reality.
