People care a lot about TV.
Case in point: The other day, I got into a conversation / disagreement over what word Ted calls Lily on How I Met Your Mother that upsets her so much. (The audience never actually hears the word because Bob Saget narrates it as "grinch".) In any case, we couldn't come to a consensus, so I decided to Google it and see what everyone else thought. And I found the most amazing thing: there were hundreds of discussion threads about it and everyone had different pieces of evidence to back up their various hypotheses.
In addition to people caring a lot about this obviously important issue, I also found that the viewers of How I Met Your Mother seem to be tamer, not to mention more intelligent and sane than the general public. Take a look at this amazing thread on the topic. Never before have American strangers had such a civil conversation about what is considered one of the more offensive words in the English language. Usually, it's the opposite: take a look at any YouTube video and without fail, the posts will devolve into some strange and unnecessary argument on a completely irrelevant and offensive topic.
I admit that a few hundred discussions about an episode of TV isn't that outrageous, so how about this? Over 12,000 people have voted on the People magazine online poll "Gossip Girl: Are Chuck and Blair Meant to be Together". Twelve thousand people (and counting) care about this. And more proof that the TV watching public is clearly of superior intelligence: 11,450 voted yes.
