Were the shows steaming when you were a kid. I think that this also impacts children a lot these days. They are never "bored" in the way they have to find something to do, make a game, get up to mischief. There is always something to watch - even if it has no value.
It was at the same time every day on the weekdays. That is why it was such a big thing, and we were excited when it was getting close to the time it airs. I think never 'bored' isn't a bad thing. Whenever we got bored, we just played with toys. I think the shows itself, with the bright visuals, and constantly changing images affect the attention span of the kids today.
