Ziff Davis Inc. (ZD) is an American magazine publisher and Internet Information company. It was founded in 1927 in Chicago by William B. Ziff, Sr. and Bernard G. Davis. Throughout most of its history, it was a publisher of hobbyist magazines, often ones devoted to expensive, advertiser-rich hobbies such as cars, photography, and electronics. However, since 1980, Ziff Davis has primarily published computer and technology related magazines, and its growing number of websites, spun off from its magazines, have established Ziff Davis as an Internet Information company.
Ziff Davis had several broadcasting properties, first in the mid-1970s, and later with its own technology network ZDTV, later renamed to TechTV, that was sold to Vulcan Ventures in 2001. Ziff Davis' magazine publishing and Internet operations offices are based in New York City, San Francisco and Woburn.
The company (Ziff Davis Media) announced that it had filed for Chapter 11 bankruptcy protection on March 5, 2008.
