Where did the tv kids go?

I noticed, anytime I watch recent tv programs at night time. They show less kids on the programs. You only see them at the beginning of the program or at the end of the program, or they been seen once or twice in an episode or two. It's mostly adults. Sometimes, the adults celebrity isn't seen as much on the tv program either. The old tv programs, show more kids than recent tv programs. Next time, you watch a recent tv program. Compared to any old tv programs, to see the difference. I even search to see if an article can tell me more about it. Only I saw about kids watching too much tv.
