The U.S. Population Is Older Than It Has Ever Been

I feel this can be seen on TV. I see a lot of characters with graying hair and aging skin on current TV. A lot more than, say, 15 years ago. I wanted to think of it as a change of taste, but I think it represens the changing average age today. Another explanation is that omainly older people are watching TV today, and so older people are casted.
