My friend just told me "It's 10PM" and naturally the next thing that popped into my head was "Do you know where your children are?" Then I started thinking... I haven't seen those public service announcements in years. Then I also started thinking about how creepy those darned things were! -And what a weird thing that was to put on TV every night. The intent is commendable, but it's still a bit odd if you think about it.
Do you know where your children are? is a popular question used as a public service announcement for parents on American television throughout the 1960s, 1970s, and 1980s, usually at 10:00PM or 11:00PM, depending on the market and/or the time of the local youth curfew. The phrase originated from Buffalo, New York's long time ABC affiliate WKBW, and was possibly inspired by the Scottish bedtime story, Wee Willie Winkie.
Besides being used on WKBW, the question became the long-running slogan of New York City TV station (and eventual Fox affiliate), WNYW, which often had celebrities saying it on camera just before the news.
