Ziff Davis, Inc.
A digital media and internet company behind familiar sites and tools like CNET, PCMag, IGN, and the Speedtest app that measures your internet connection. Its roots go back to a Chicago publishing house founded in 1927 by William Ziff and Bernard Davis, which began with hobbyist magazines like Amazing Stories. The modern company grew from j2 Global, which bought the Ziff Davis name in 2012 and later renamed itself after that original publisher.
