Throughout most of Ziff Davis' 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. On November 12, 2012, Ziff Davis Inc., was acquired by cloud computing services company j2 Global of Hollywood, Calif. for $167 million in cash.
