The former, premier computer trade show in the U.S. Although it grew into an end user event, it was originally created for dealers and distributors (it was the COMputer Dealers EXposition). COMDEX was originally developed by The Interface Group, which was acquired by Japanese SOFTBANK Corporation in 1995, and then by Key3Media Group in 2001.

After financial struggles that resulted in temporary bankruptcy, Key3Media renamed itself MediaLive International, Inc. in 2003. A new management team canceled COMDEX 2004 in Las Vegas and commissioned an independent survey of IT buyers in order to redesign the event for maximum effect. In 2010, COMDEX re-emerged as COMDEX Virtual, an online presentation simulating the live event. See COMDEX Virtual.

Fall COMDEX - Las Vegas
In 1979, the first Fall COMDEX had 157 exhibitors and 4,000 attendees. By the turn of the century, it had grown to more than 2,000 exhibitors and 200,000 attendees, but by 2003, tapered off to less than a quarter of those numbers due to the high tech slump.

In its heyday, Fall COMDEX was a spectacular event. Housed in two Las Vegas convention centers and several hotels, shuttle buses escorted attendees between venues. Waiting in lines for a bus was legendary, although often a welcome relief after walking the lengthy corridors.

COMDEX/Spring was first held in New York in 1981 with 237 exhibitors and 11,000 attendees. Subsequent events were held in various locations including Atlantic City, Atlanta and Chicago. See trade shows.
