While the Warner Bros. name and logo has remained largely unchanged for almost a century, its parent company has undergone frequent name changes in recent years. Warner Communications merged with Time Inc. to become Time Warner in 1990. Then Time Warner was purchased by AOL at the very apex of the dot-com boom, creating AOL Time Warner. AOL later spun off Time Warner, which was eventually acquired after some legal wrangling by AT&T, who rebranded it as WarnerMedia. Just a few years later, the company will need to update all their letterhead yet again.
