In 1998, the publication was renamed to Macworld, incorporating MacUser to reflect the consolidation of the Ziff-Davis-owned MacUser magazine into the International Data Group-owned Macworld within the new Mac Publishing joint venture between the two publishers. That year, the new company also purchased the online publication MacCentral Online, because Macworld didn't have a powerful online component at the time. Sometime later the name was changed again to Macworld.
The magazine is published in many countries, including Australia (Australian Macworld), France, Germany (Macwelt), Italy (Macworld Italia), Spain, Sweden(MacWorld), and the United Kingdom. Its content is incorporated into a number of other IDG publications.
The magazine's publisher licenses its name to another IDG subsidiary, IDG World Expo, for the Macworld Conference & Expo, which takes place twice annually in North America.
