A UNESCO study said that "Terminator," the killer robot played by American actor Arnold Schwarzenegger, is the most popular character among the world's children. The survey, billed as the first ever worldwide study of violence in the media, said a stunning 88 percent of children around the world know "Terminator." The survey said television was the strongest single factor creating a global culture, and the omnipresence of violence on the box was contributing to making the world more violent.
