5 Most Famous Monopolies Of All Time

3. AT&T

AT&T is the biggest telecommunication company in the world right now, and that is after being broken up by the Supreme Court. Even today, it is the biggest provider of mobile phone and fixed phone services in the United States. AT&T was a subsidiary of the Bell Telephone Company, which was founded by Alexander Graham Bell. However, the company grew to such a significant size that in 1982, there was a United States v AT&T antitrust lawsuit, which resulted in the breakup of the company into smaller parts, including the divesture of what were known as ‘Baby Bells’, which became independent companies. The current AT&T is made up of 10 out of the original 22 Bell Operating Companies.
