PCWorld is a global computer magazine published monthly by IDG. It offers advice on various aspects of PCs and related items, the Internet, and other personal-technology products and services. In each publication, PCWorld reviews and tests hardware and software products from a variety of manufacturers, as well as other technology related devices such as still and video cameras, audio devices and televisions.

The current editorial director of PCWorld is longtime tech journalist Steve Fox, effective with the December 2008 issue of the magazine. He replaced the magazine's veteran editor Harry McCracken, who resigned that spring, after some rocky times, including quitting and being rehired over editorial control issues in 2007.

PCWorld is published under other names such as PC Advisor and PC Welt in some countries. PCWorld's company name is IDG Consumer & SMB, and it is headquartered in San Francisco.

The publication was announced at the COMDEX trade show in November 1982, and first appeared on newsstands in March 1983; Felix Dennis set up Personal Computer World which he later sold to VNU, and established MacUser which he sold to Ziff Davis Publishing in the mid-eighties. PC Magazine was also acquired by Ziff Davis.

World Magazines are magazines about specific foreign countries that help people of different countries, languages, and cultures to understand that country. Magazines that focus on many different countries from the perspective of the reader country are not 'World Magazines.' They are 'Global Magazines,' while magazines that are sold in many countries, but with no consistent focus on the culture and society of one country, are 'International Magazines.'

For example, a person in America wishing to learn about Japan could pick up the National Geographic, which is both a global and an international magazine, but only if it had a feature on Japan. Someone with a stronger commitment to understanding that country would be better advised to subscribe to a magazine that focuses entirely on Japan but with articles in his native tongue, unless, of course, he was bilingual.

If he was an English speaker, he could select a magazine like Tokyo Journal or Kyoto Journal, both of which are produced in Japan in English. A German reader would be able to choose Japanmarkt, although this is limited to business issues, rather than cultrual and social areas. Someone wishing to undersytand more about Azerbaijan could subscribe to Azerbaijan International. Although this is not produced in Azerbaijan, it focuses entirely on Azerbaijan and helps to promote understanding of that country, so it is therefore a world magazine. Indeed, often, due to limitations on the freedom of the press or security issues, a World magazine may need to be based in a foreign country.
