Answer:
Argumentum ad populum
Step-by-step explanation:
Argumentum ad populum is a logical fallacy that seeks to confirm information based on the number of people who are associated with it. In other words, this fallacy states that if most people do a certain thing, it is because that thing is correct. An example of this can be seen in the question above, where the narrator states that if millions of people watch a tv show, it is not possible that this show is inappropriate, because it is not possible that millions of people are wrong about the same cause.
