PC Magazine (or PC Mag) is a computer magazine 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 Louderback had held this position since 2005, but accepted the position of CEO of Revision3, an online media company.
