Ziff Davis: A Century of Media Evolution from Aviation to AI
The story of Ziff Davis is a mirror of the modern media landscape. What began as a small Chicago advertising agency in 1920 has transformed over a century into a global digital powerhouse. From the golden age of pulp magazines and aviation journals to the cutting edge of internet broadcasting and AI litigation, the company has consistently pivoted to capture the interests of the modern consumer.
The Early Years: Aviation and the Birth of a Publishing Empire
The company's roots trace back to the William B. Ziff Company, founded in 1920. Initially focusing on advertising for African American weekly newspapers, the firm expanded into publishing in 1923 by acquiring the E. C. Auld Company. After early experiments with humor magazines, William Ziff—a World War I aviator—launched Popular Aviation in August 1927.
Under the guidance of editor Harley W. Mitchell, Popular Aviation became a dominant force in the industry, reaching a circulation of 100,000 by 1929. The title underwent several name changes, including Aeronautics, before eventually becoming Flying in 1942, a publication that celebrated its 90th anniversary in 2017.
The formal transition to the "Ziff-Davis Publishing Company" occurred in 1936 when B.G. Davis joined the firm. Davis, a photography enthusiast, expanded the company's reach by launching Popular Photography in May 1937.
Diversification into Fiction, Hobbies, and Comics
In 1938, Ziff-Davis entered the realm of science fiction and electronics by acquiring Radio News and Amazing Stories from the bankrupt Experimenter Publishing. These titles were revitalized under Ziff-Davis, leading to the creation of Popular Electronics in 1955 and the science fiction companion Fantastic Adventures.
The 1950s saw a brief but notable foray into comic books. Operating under their own name and Approved Comics, the company avoided superheroes in favor of horror, crime, romance, and Westerns. Notable industry figures, including Superman co-creator Jerry Siegel, served as art directors. While most titles were sold to St. John Publications by 1953, the G.I. Joe comic continued until 1957.
Following the death of Bill Ziff in 1953, his son, William B. Ziff Jr., took the helm. The company continued to diversify, launching HiFi and Music Review (which became Stereo Review) and entering the bridal market with Modern Bride.
The Digital Pivot and the Rise of Tech Media
As the personal computing revolution took hold in the 1970s and 80s, Ziff Davis positioned itself as the leading authority on technology. The acquisition of PC Magazine in 1982 and MacWEEK in 1988 solidified this status. This era marked the transition from print to digital, beginning with ZiffNet in 1991 and the launch of ZDNet in 1994.
The company also experimented with television. In 1994, it launched The Personal Computing Show on CNBC. By 1998, Ziff-Davis launched ZDTV, a 24-hour interactive cable network. Despite critical acclaim and an investment from Microsoft co-founder Paul Allen, ZDTV struggled with cable carriage fees and was eventually sold to Vulcan Ventures in 2000.
Corporate Restructuring and Modern Acquisitions
The early 2000s were a period of volatility. After being acquired by CNET Networks in 2000, the Ziff Davis brand underwent various ownership changes and a Chapter 11 bankruptcy filing in 2008 to restructure debt. However, the company rebounded under new ownership, including Great Hill Partners and later J2 Global.
Under J2 Global (which rebranded back to Ziff Davis, Inc. in 2021), the company aggressively acquired digital properties to build a massive media ecosystem. Key acquisitions included:
- IGN Entertainment (2013)
- Ookla (2014), owner of Speedtest.net
- Mashable (2017)
- RetailMeNot (2020)
- CNET and ZDNet (2024)
By 2018, the company reached a global scale with 117 million readers across 115 countries. Recent years have seen further expansion into lifestyle and news with the acquisitions of Lifehacker, The Skimm, Well+Good, and Livestrong.
