The shows were initially organized by Commodore Canada or its sister companies, and took place at the International Centre in Mississauga, Ontario, though in some years additional expos were held in the United States, Australia, or Europe.

[3] As with cross-industry trade shows such as CES and COMDEX, World of Commodore expos were widely reported on in computing magazines.

The name was changed to World of Amiga following Commodore's bankruptcy in 1994 and purchase by German PC conglomerate Escom the following year.

[1][9] World of Commodore II was held from 29 November to 2 December 1984 at the International Centre in Mississauga and attracted 41,516 visitors.

[12] The expo also hosted the usual slate of seminars, with presentations by Commodore, Digital Solutions, TPUG, Jim Butterfield, Steve Punter, and others.

Industry exhibitors included Abacus Software, Ahoy!, Commodore Business Machines, Digital Solutions, Electronic Arts, Gold Disk, Grolier, McGraw-Hill Ryerson, TPUG, Watcom, and WordPro distributor Norland Agencies.

Hardware developers and vendors were out in force, with Mimetics demoing a Deluxe Music Construction Set–compatible MIDI sequencer, and Xetec presenting its SCSI interfaces and hard drives.

Notable personages in attendance included author Jim Butterfield, Commodore engineer Dave Haynie, and sysops from Commodore-related forums on The Source and CompuServe.

There were over 85 exhibitors, including TPUG, Ahoy!, Electronic Arts, The Transactor, NewTek, Supra, Inc., Gold Disk, Xetec, and Commodore itself.

[14][15] New productivity software exhibited at the show included Berkeley Softworks's geoPublish, Electronic Arts's PaperClip III and Mavis Beacon Teaches Typing, and NewTek's Video Toaster.

[15] New games for the Commodore 64 and 128 came mostly from Electronic Arts, and included Halls of Montezuma, Bard's Tale III, Skyfox II, Strike Fleet, and Skate or Die.

[2] 1988 marked the first time that two World of Commodore expos were held: one in November at the Philadelphia Civic Center,[16] and the other in December in Toronto.

[22] Third-party exhibitors releasing and demonstrating new products included SAS Institute, Scala, Inc., Gold Disk, and Digital Creations.

[3][24] Though the expo included a special anniversary celebration for the Commodore 64, only a very small minority of exhibitors and visitors were 8-bit computer users.

[27] At the Pasadena show, Commodore US President Jim Dionne outlined his plans for Amiga CD32 sales to bring the company back into profit.

[4][6] The event was held at the Belaire Hotel in Toronto on 4 December, and featured talks and demos by Jim Butterfield, Jim Brain, Jeri Ellsworth, former Transactor editor Karl J. H. Hildon, Commodore Canada vice president Ron Anderson, and a representative of Commodore trademark holders Tulip Computers.

It featured screenings of the TVOntario series Bits and Bytes,[6] a guest talk by C64 Direct-to-TV designer Jeri Ellsworth,[34] and the final World of Commodore appearance by author Jim Butterfield.

The event, held on 1 December 2007, featured several tributes to Commodore pioneer Jim Butterfield, who had died of cancer earlier that year.
