PC Magazine (sometimes referred to as PC Mag) is a computer magazine that is published monthly (until 2008 it was published biweekly except in January and July) both in print and online. The magazine is published by Ziff-Davis Publishing Holdings Inc. The first edition was released in January 1982 as a monthly called PC (the "Magazine" was not added to the logo until the first major redesign in January 1986). The magazine moved to biweekly publication in 1983 after a single monthly issue swelled to more than 800 pages.

The magazine's editor-in-chief, Lance Ulanoff, ascended to his current post in July 2007. Jim Louder back had held this position since 2005, but accepted the position of CEO of Revision3, an online media company.
