UniForum, which put out an request for proposals last week, claims it has six to eight alternative show managers to replace IDC World Expo, which quit the day after the last show closed. Contrary to reports circulating, it says, it has not been turned down by The Interface Group or Blenheim Exhibitions Group. In fact, it says the Interface Group, which owns Comdex, is quite interested. It has not talked to Blenheim yet, but its ownership of Unix Expo could be a problem if Blenheim wants to put a Unix Expo on the West Coast. There are also concerns about the impact that Dallas, next year’s venue, will have. Meanwhile, UniForum wants everyone to note that paid attendance on the conference side of the show was up 65% this year to 1,850.
