"Do you know where your children are?" is a question used as a public service announcement (PSA) for parents on American television especially from the late 1960s through the late 1980s. Accompanied by a time announcement, this phrase is typically used as a direct introduction for the originating station's late-evening newscast, typically at either 10:00 p.m. or 11:00 p.m.[1] Wikipedia: https://en.m.wikipedia.org/wiki/Do_you_know_where_your_children_are%3F
