United States v. AT&T Inc.

United States v. AT&T Inc. was a landmark antitrust case in 1982, where the U.S. government sued to block AT&T's attempt to acquire RCA, arguing it would harm competition and consumer choice in telecommunications. The case led to the breakup of AT&T's monopoly, resulting in the divestiture of its regional phone companies into independent entities called "Baby Bells." This restructuring aimed to foster competition, innovation, and lower prices in the U.S. telecommunications industry. The case is significant for shaping telecom regulation and preventing monopolistic dominance.
