On April 30, 1907, Theodore Newton Vail returned as President of AT&T. Vail believed in the superiority of one phone system and AT&T adopted the slogan "One Policy, One System, Universal Service." This would be the company's philosophy for the next 70 years.
Under Vail, AT&T began buying up many of the smaller telephone companies including Western Union telegraph. Anxious to avoid action from government antitrust suits, AT&T and the federal government entered into an agreement known as the Kingsbury Commitment.
The Bell trademark (pictured right) used by both the AT&T corporation and the regional operating corporations from 1921 to 1939 to co-brand themselves under a single Bell System trademark would have the regional operating corporation's name where the "name of associated company" appears in this boilerplate version of the trademark. Phones themselves were made by Western Electric, a wholly-owned subsidiary of AT&T, who also owned or controlled the local Bell System companies responsible for local phone service. Member telephone companies paid a fixed fraction of their revenues as a license fee to Bell Labs.
As a result, by 1940 the Bell System effectively owned most telephone service in the United States, from local and long-distance service to the telephone itself. With control of the phone system, Bell could effectively prohibit its customers from connecting to the system without leasing fees phones not made or sold by Bell companies. For example, if a customer desired a type of phone not leased by the local Bell monopoly, one had to purchase the phone at cost, give it to the phone company, then pay a 're-wiring' charge and a monthly lease fee in order to use it. An oft-heard remark at the time was "Ma Bell has you by the calls". A 1956 consent decree, to which AT&T and the United States Department of Justice agreed as a resolution of an antitrust lawsuit filed in the United States in 1949, limited AT&T to engaging in only activities related to a maximum of 85% of the United States' national telephone network and certain government contracts, which precluded the Bell System from extending its reach into the fledgling computer industry and from continuing to hold interests in Canada and the Caribbean. The Bell System's Canadian operations included the Bell Canada regional operating company and the Northern Electric manufacturing subsidiary of the Bell System's Western Electric equipment manufacturer. Northern Electric and Bell Canada were spun off in 1956 as separate companies outside of the Bell System proper. The Bell System's Caribbean regional operating companies were sold to the International Telephone & Telegraph Co., later known as ITT.
The Bell System also owned various Caribbean regional operating companies, as well as 54% of NEC and a post-WW II re-construction relationship with NTT before the 1956 boundaries were emplaced. Before 1956, the Bell System's reach was truly gargantuan, as the list below of now-divested formerly-held corporations indicates. Even during the period from 1956 to 1984, the Bell System's dominant reach into all forms of communications was pervasive within the United States and influential in telecommunication standardization throughout the industrialized world.
The 1984 Bell System divestiture that brought an end to the affiliation branded as the Bell System was the result of a lawsuit alleging illegal practices by the Bell System companies to stifle competition in the telecommunications industry; the lawsuit was brought against it by the United States Department of Justice (DOJ). That lawsuit was filed in 1974, and was settled on January 8, 1982, displacing the former restrictions that AT&T and the DOJ had agreed to in 1956 based on a previous anti-trust lawsuit filed by the DOJ in 1949 that alleged that AT&T and its Bell System operating companies were using its near monopoly in telecommunications to attempt to establish allegedly unfair advantage in related technologies, especially the fledgling computer industry.
Prior to the 1984 break-up that ended the Bell System, the Bell System included not only AT&T corporate and its long-lines long-distance routing but also Bell Operating Companies.
Of the various resulting 1984 spinoffs, only BellSouth actively used and promoted the Bell name and logo for its entire history, from the 1984 break up to its merger with the new AT&T in 2006. Similarly, cessation of using either the Bell name or logo occurred for many of the other companies more than a decade after the 1984 break up as part of an acquisition-related rebranding. The others have only used the marks on rare occasions to maintain their trademark rights, even less now that they have adopted names conceived long after divestiture. Examples include Verizon, which still uses the Bell logo on its trucks and payphones, and Qwest, formerly US West, which licenses the Northwestern Bell and Mountain Bell names to Unical Enterprises, who makes telephones under the Northwestern Bell name. Qwest also has a rural subsidiary in Oregon, Malheur Bell, that continues to use the Bell name and logo.
Cincinnati Bell, a local franchise of the Bell System that was never wholly owned by AT&T and existed separately prior to 1984, also continues to use the Bell name. It stopped using the Bell logo in the summer of 2006, though it is still seen on some bills, vehicles, and other literature.
In 1984, each regional Bell operating company was assigned a set list of names they were allowed to use in combination with the Bell marks. Again, aside from Cincinnati Bell and Malheur Bell, none of these Bell System names are currently in use in the United States. For example, Southwestern Bell used both the Bell name and the circled-bell trademark until SBC opted for all of its companies to do business under the "SBC" name in 2002. Bell Atlantic used the Bell name and circled-bell trademark until renaming itself Verizon in 2000.
Telephone Companies outside of the Bell System that use "Bell" in their names include PBX telephone dealer near Lake of the Ozarks, Missouri, called Missouri Bell Telecom which was established during 1991, and Liberty Bell Telephone.
Of the various resulting 1956 spinoffs, only Bell Canada continues to use the Bell name, although cessation of using either the Bell name and circled-bell trademark occurred for some of these companies multiple decades later. For example, for the multiple decades that Nortel was named Northern Telecom, their research and development arm was Bell Northern Research. Bell Canada and its holding-company parent, Bell Canada Enterprises, still use the Bell name and used variations the circled-bell logo until 1977, which until 1976 strongly resembled the 1921 to 1939 Bell System trademark shown above.
Beginning in 1991, the Baby Bells began to consolidate operations or legally rename their Bell Operating Companies according to the parent company name, such as "Bell Atlantic – Delaware, Inc." or "U S West Communications, Inc.", to "unify" the corporate image. To this day, the only remaining Baby Bell that has not renamed its operating companies is AT&T, formerly SBC Communications. Since 1995, there have only been 19 Bell Operating Companies, following the mergers of US West's and BellSouth's operating companies. Only 9 of those 19 have retained their original corporate name since their incorporation before 1984.
Before the 1956 break-up, the Bell System also included the companies listed below. Bell Canada, Northern Electric, and the Caribbean regional operating companies were considered part of the Bell System proper before the 1956 break-up. Nippon Electric was considered a more distant affiliate of Western Electric than Northern Electric, where Nippon Electric via its own research and development adapted the designs of Western Electric's North American telecommunications equipment for use in Japan, which to this day gives much of Japan's telephone equipment and network a closer resemblance to North American ANSI and Telcordia standards than to European-originated ITU-T standards. Before the 1956 break-up, Northern Electric was predominantly focused only on manufacturing without any significant amount of separate telecommunication-equipment research & development of its own. The post-WWII-occupation operation of NTT was considered an administrative adjunct to the North American Bell System.

These are verifications of proof these companies that carry the "Bell" label outside the Bell System exist.
