Often on OTA TV you see nothing but ads for "old people" products, not just things that "old people dig" (Black Sabbath?) but for things aimed at the indignities of age (adult diapers, ...) as well as the people who will file a fake medicare claim on your behalf,...

You could easily got the whole day and see mostly ads for things you could spend government services on, lawyers who might help you if you are hit by a car (and you have a slam dunk case) -- the one thing you might see advertised that people spend their own money on is cars. I guess if they didn't have any cars nobody would get hit by a car and need a personal injury lawyer. Scam and near-scam financial services targeted at the elderly is another big theme.

Add that up and if you're under 50, TV sends messages that "I want to die before I get old", "everybody else is just out to chisel from the government", etc. It makes me wonder if taking Grandma's phone away so she can't get scammed is worth her not being able to call 911.

Because there is no ad targeting by age on TV, TV is flooded by old people ads that drive away even a middle aged audience. By the time we get old we won't be watching TV because of it. If TV had age-targeted ads it might be tolerable to watch again.
