[buenos aires] Argentina's top tobacco companies are marketing their brands with Hollywood blockbusters, rock concerts and other events following a voluntary ban on TV and radio advertising that started Jan. 1, 2003. Argentina is one of the last countries to outlaw tobacco advertising on TV. Market leader Massalin Particulares, a unit of Altria Group's Philip Morris International, is giving customers sneak previews of films like "About Schmidt" and "The Quiet American" at a Buenos Aires movie theater branded for the occasion as Philip Morris Cinema. Consumers get a ticket, popcorn and soft drinks in return for showing proof of purchase of Philip Morris-branded cigarette cartons. Rival Nobleza Piccardo, a unit of British American Tobacco, staged a rock festival to promote its Pall Mall brand.
