MacWorld Magazine - March 2009

Macworld is a web site and monthly computer magazine dedicated to Apple Macintosh products. It is published by Mac Publishing, which is headquartered in San Francisco, California. Published since 1984, the magazine has the largest audited circulation (both total and newsstand) of Macintosh-focused magazines in North America, more than double its nearest competitor, Mac|Life (formerly MacAddict). Macworld was founded by David Bunnell (publisher) and Andrew Fluegelman (editor). In 1997, the publication was renamed to Macworld, incorporating MacUser (a name reflected subtly on the magazine's Table of Contents page) 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. In 1999, the combined company also purchased the online publication MacCentral Online, because Macworld didn't have a powerful online news component at the time. In late 2001 International Data Group (IDG) bought out Ziff-Davis' share of Mac Publishing, making it a wholly owned subsidiary of IDG.
