In some regions of the world, both the positive "OK" and the negative forms are practiced, which can lead to confusion over which meaning is intended. In regions and cultures where the gesture has a historically negative connotation, its use as an "OK sign" is often the result of its appearance in media and tends to be used more by younger people. In France, where widespread use has seeped in through American culture, the gesture's positive "OK" sentiment became popular in the north of the country while its negative connotation as "worthless" remained in the south. To avoid confusion, French communicators have become accustomed to using additional context clues, such as posture or facial expression, to clarify meaning. In other circumstances, the gesture's varied meanings are less easily reconciled, as was the case in 1950s Brazil when United States Vice President Richard Nixon emerged from his airplane displaying the sign with each hand. While Nixon's intent was to communicate goodwill to the people of São Paulo, the crowd received it with offense.
