Founding Story

The company's assets come from two lineages. Warner Bros. Pictures was founded in 1923 by brothers Harry, Albert, Sam and Jack Warner, and became part of Time Warner, which later added HBO, CNN and the Turner networks. AT&T bought Time Warner in 2018 and renamed it WarnerMedia. Discovery began with the Discovery Channel, which John Hendricks launched in 1985, and grew under CEO David Zaslav, including the 2018 purchase of Scripps Networks Interactive. In April 2022 AT&T spun off WarnerMedia and merged it with Discovery, creating Warner Bros. Discovery with Zaslav as CEO.
