When you watch people for cumulative hours, you get an idea of who they are.

And you get an idea of their tastes & whether or not you share the same tastes. Back in the day, if Siskel & Ebert gave a film two thumbs up, I would probably go see it. Not because they were on the TV, not because of some credentials they may or may not have had, but because over time, I've found out that I generally liked the films they gave two thumbs up, and life is too short to "do my own research" on all the movies playing this weekend.

Of course, this doesn't mean I would go out and buy a car if they were in the commercial for it, but I might have thought about getting a movie related product they hawked (microwavable popcorn? Special edition VHS/DVD? I dunno...).
