Bandwagon Fallacy, also known as argentum ad populum is a type of fallacy that concludes that a proposition has no option but to be true if it is done or endorsed by a large number of people or if most people are already doing it, then it must be true.
Therefore, the statement, "If they are so corrosive and decadent how could millions of people tune in?" is a Bandwagon Fallacy because it believes that because millions of people tune in, that makes it less corrosive and decadent.
