Map of the original and current companies.
The 'Regional Bell Operating Companies' ('RBOC') are the result of the U.S. Department of Justice
antitrust suit against
American Telephone & Telegraph.
History
On
January 8,
1982, AT&T settled the suit and agreed to divest ("spin off") its local exchange service operating companies in return for a chance to go into the Internet services industry. Effective
January 1,
1984, AT&T's local operations were split into seven independent Regional Bell Operating Companies known as "Baby Bells." RBOCs were originally known as 'Regional Holding Companies', or 'RHCs'
[1].
After the
Modification of Final Judgment, the resulting ''Baby Bells'' were originally:
★
Ameritech — (acquired by
SBC in 1999)
★
Bell Atlantic — (acquired
GTE in 2000 and changed its name to
Verizon)
★
BellSouth — (acquired by
AT&T in 2006)
★
NYNEX — (acquired by Bell Atlantic in 1996)
★
Pacific Telesis — (acquired by SBC in 1997)
★
Southwestern Bell — (changed its name to SBC in 1995; acquired
AT&T in 2005 and changed its name to
AT&T)
★
U S West — (acquired by
Qwest in 2000)
Prior to 1984, AT&T also held investments in two smaller and otherwise independent companies,
Cincinnati Bell and
Southern New England Telephone (SNET). Following the 1984 breakup, these became fully independent as well. All nine local-exchange companies were assigned a share of the rights to the Bell trademark. Additionally, there was one comparably-sized independent (non-Bell) company,
GTE.
Shared Trademarks
After divestiture AT&T was prohibited from using the Bell name or logo, and those trademarks would be shared by the RBOCs. After the BellSouth acquisition, Cincinnati Bell and Bell Canada are the last former AT&T companies to still carry the "Bell" name.
Current use of the Bell logo includes
Verizon who uses the Bell logo on its payphones (including former
GTE payphones), hard hats, trucks, and buildings. Additionally,
Malheur Bell, a
Qwest-owned independent uses the Bell name and logo.

Mergers

This diagram shows how the various RBOC companies have changed due to mergers and acquisitions since the 1984 breakup.
Many of these companies have since merged, leaving only 3 regional telephone companies in the United States. After the 1984 breakup, part of AT&T's
Bell Labs was split off into
Bellcore, which would serve as an R&D and standards body for the seven Baby Bells.
AT&T Inc.
Southwestern Bell Corporation, which changed its name to
SBC Communications in
1995, acquired
Pacific Telesis in
1997, former independent Bell System franchise not part of divestiture,
SNET in
1998, and
Ameritech in
1999. In February 2005, SBC announced its plans to acquire former parent company
AT&T Corporation for over $16 billion. SBC took on AT&T name upon merger closure, which closed on
November 18,
2005. SBC began trading as
AT&T, Inc. on
December 1,
2005 but began re-branding as early as November 21. On
March 5,
2006, it was announced that
AT&T would purchase BellSouth for $67 billion U.S., in an all-stock deal. On
December 29,
2006, the
FCC approved the merger, worth $86 billion US.

Verizon Communications
In 1997,
NYNEX was acquired by
Bell Atlantic (taking the
Bell Atlantic name), which later, in 2000, merged with
GTE, the largest independent telephone company, to form
Verizon. In 2005, following a protracted bidding war with rival RBOC Qwest, Verizon announced that it would acquire long distance company
MCI. The Verizon and MCI merger closed on
January 6,
2006.
On
January 16,
2007, Verizon announced that it would split off
Verizon New England operations in
Maine,
New Hampshire, and
Vermont into a separate operating company, which then will be spun off and merged with
FairPoint Communications. The deal is currently pending approval.
Qwest
In 2000,
US West was merged into
Qwest, a
Denver-based
fiber optics long-distance company.
Cincinnati Bell
★ The former independent
Bell System franchise
Cincinnati Bell, which was not part of the 1984 divestiture because AT&T only held a minority stake in the company, remains independent of the RBOCs.
Bell Canada
★
Bell Canada was divested from AT&T in 1956 and not part of the 1984 agreement.
Notes
# The acronym 'RHC' for 'Regional Holding Company' is also sometimes seen.
