Las Vegas rules the convention business

The statistics are interesting:

In 1991, New York City held 30 of the 200 biggest trade shows, as defined by Tradeshow Week magazine. Chicago held 28, and Las Vegas, 22.

In terms of exhibit space use, Chicago accounted for 20 percent, Las Vegas for a little more than 14 percent and New York City, 13 percent.

Since then, Las Vegas has exploded in winning the top shows. In 2004 it held 38 of the top 200 shows, and accounted for almost a third of exhibit space use in the nation. In 2001, 40 of the top 200 shows were held in Las Vegas.

The mob,unions,and cold weather probably don't help those old cities.Bloomberg
