Do you know where your children are? is a popular question used as a public service announcement for parents on American television. Its heyday was throughout the 1960s, 1970s, 1980s, but has made a comeback as of late. The question is usually asked around 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.
WKBW news director Irv Weinstein is said to have begun using the phrase at the beginning of his career in the early 1960s, at the suggestion of a local viewer. WKBW used the phrase until 2003, when virtually all of its old image was scrapped in favor of a newer package, and returned to the phrase as a partial return to its old package in 2008.
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; some other stations owned by Fox and Local TV LLC also use the phrase. In 2007 WDIV in Detroit started using the phrase at the beginning of its 11 o'clock newscasts. WTXF-TV FOX29 in Philadelphia also uses the phrase at the beginning of its 10 o'clock newscast.
