In 1882, it became a subsidiary of American Bell Telephone (the parent company of the Bell System). In 1900, when the company was absorbed by AT&T (American Telephone and Telegraph Company), it also became a subsidiary of AT&T (still a wholly owned subsidiary).

From AT&T

...The largest telecommunications company in the United States, AT&T operates a mobile phone service (AT&T Wireless Service) and an Internet service (AT&T WorldNet) with long-distance business at its core, and is also focusing on overseas business, expanding its partnerships with major telecommunications companies around the world under the name "World Partners." The company was established in 1885 as a 100% subsidiary of the American Bell Telephone Company, which was founded by Alexander Graham Bell, with the aim of providing long-distance services (its name at that time was AT&T (American Telephone and Telegraph Company) (there is no full name that corresponds to the current AT&T)).
