Media consultant Tony Schwartz, a creator of famed political ad "Daisy" (left), died Saturday of a heart condition. He was 84. From his home in Manhattan, Schwartz created not only infamous "Daisy" for Lyndon Johnson but also ads for Jimmy Carter and Bill Clinton, among other mostly Democratic politicians. According to the Times, "detractors and admirers alike praised Mr. Schwartz as a pioneer in putting sound to more effective use in television advertising. He was credited, for instance, with being the first to use real children’s voices in television commercials, beginning in the late 1950s." Daisy is considered not only the most famous political ad of all time, but also one of the first and most influential negative ads. [Times]
