IDG World Expo's Greco reportedly quitting "The Chief executive of IDG World Expo is quiting his post, in the midst of delicate negotiations to persuade Apple Computer, Inc. to attend IDG's MacWorld trade show in Boston next year, according to a published report. In an electronic mall bulettin to subcribers, Tradeshow Week magazine reported that Greco is leaving Framingham based IDG World Expo for another position in the event managment industry, and that IDG had begun seeking a replacement. Last year, Greco worked out a deal with Menino and city convention officials to return MacWorld to Boston in 2004, as the first tenant of the city's mew convention center, now under construction. But Apple Computer shocked the city by declaring that it would not take part in a MacWorld in Boston, and might abandon the 2003 MacWorld in New York. Since then, Greco has been in Negotiations with Apple, hoping to reverse this decsion. It's unclear how Greco's departure would affect the future of MacWorld Boston. An Apple spokesperson said the company had not yet assessed the impact of Greco's resignation." Boston Globe 2/5/03 Any ideas on the impact.
