AT&T

AT&T is among the world’s largest telecommunications companies, offering wireless communications, broadband internet, and entertainment services. The company held a decades-long telephone monopoly in the U.S. before a 1982 antitrust settlement broke it into parts. In 2023, AT&T was the world’s largest telecommunications company by revenue. In 2022, AT&T finished merging its spinoff WarnerMedia with Discovery, a reorganization that resulted in the creation of Warner Bros. Discovery.
