Publish Date: 05/06/1991 Headline: none Nintendo challenge begins today The Nintendo Campus Challenge will invade Coffman Memorial Union Plaza from 9 a.m. to 3 p.m. today and tomorrow. Students will compete on a variety of Nintendo games at 64 regular game machines or 48 Game Boy units, which will be housed in large trailers. The top scorer wins an all-expense-paid trip to Florida for the national championship. Nintendo and General Motors Corp. are sponsoring the 50-city, $3 million tour, according to Melissa Matthews, a spokesperson for Nintendo. Four student groups are sponsoring the tour's University stop: the Undergraduate Marketing Association, the University Advertising Club, the Society for the Advancement of Management and the Business Association for Minorities. Ad Club member Steven K. Fromme said the group's members are organizing the competition to gain practical experience in their fields. Nintendo is sponsoring the event to get exposure for their games at the college level, Matthews said. Matthews also praised the efforts of the organizers. "This is one of the best groups we have worked with. At other places, we had to take the sponsors through the process step by step, but they were really well organized," she said. --Ed Huyck
