Where Did They Go?

Growing up, I remember there were always ads on tv for kids to take their vitamins. They were in cartoon shapes so kids would take them. Are those commercials still on tv anymore? Did they decide that they didn't make as much money off of healthy kids as they did with unhealthy kids? I don't think my kids have seen anything like that on tv. I know when I talk about that stuff in the future, I'm going to get some really weird looks from my kids.
