    I think they had that phrase on WWII propaganda posters as well. More to do with potential espionage of enemy countries, though.

    Edit: totally wrong, it was coined on Sept 12, 2001 by New York advertising executive Allen Kay.

      Oh ok so I had the source wrong, that’s quite an effective ad exec.

      It definitely was a major background color to the early 2000s atmosphere.
