A long time ago in a galaxy far far away... OK so just across the border in the U. S. of A., TV stations had this creepy 'Do you know where your children are?' thing going on.
For several years throughout the 70's, here in Indy, every station's 10pm newscast was prefaced by an announcer doing the same "do you know where your children are?" shtick. It was to remind everyone that minors were subject to curfew laws. They had to be home (or otherwise off the streets) by 10pm.
