Two U.S. businessmen recently decided to launch a "Made in America" campaign using the A-OK sign as its emblem. The problem, say Lennie Copeland and Lewis Griggs, San Francisco co-producers of "Going International," a film about cultural biases, was that the gesture has vulgar sexual connotations in several European and African countries. And while America means the United States to people in this country, it designates residents of the Northern and Southern hemispheres to the rest of the world. Needless to say, the campaign was scrapped.
