History of AT&T

History of AT&T is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand History of AT&T rather than just read about it. In short: The history of AT&T originates in the invention of the telephone. The Bell Telephone Company was established in 1877 by Alexander Graham Bell, who was granted the first U.S. patent for what became the telephone, and his father-in-law, Gardiner Greene Hubbard.

Key takeaways

  • History of AT&T belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect History of AT&T to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of History of AT&T from memory before moving on to harder problems.

Reference excerpt

The history of AT&T originates in the invention of the telephone. The Bell Telephone Company was established in 1877 by Alexander Graham Bell, who was granted the first U.S. patent for what became the telephone, and his father-in-law, Gardiner Greene Hubbard. Bell and Hubbard also established American Telephone and Telegraph Company in 1885, which acquired the Bell Telephone Company, and became the primary telephone company in the United States. This company maintained an effective monopoly on telephone service in the United States until anti-trust regulators agreed to allow AT&T to retain Western Electric and enter general trades computer manufacture and sales in return for its offer to split the Bell System by divesting itself of ownership of the Bell Operating Companies in 1982. AT&T Corporation was eventually purchased by one of the Regional Bell Operating Companies, the former Southwestern Bell Company, in 2005, and the combined company became known as AT&T Inc.

Origins

The formation of the Bell Telephone Company superseded an agreement between Alexander Graham Bell and his financiers, principal among them Gardiner Greene Hubbard and Thomas Sanders. Renamed the National Bell Telephone Company in March 1879, it became the American Bell Telephone Company in March 1880. By 1881, it had bought a controlling interest in the Western Electric Company from Western Union. Only three years earlier, Western Union had turned down Gardiner Hubbard's offer to sell it all rights to the telephone for $100,000 ($3.34 million in 2009 dollars). In 1880, the management of American Bell created what would become AT&T Long Lines. The project was the first of its kind to create a nationwide long-distance network with a commercially viable cost-structure. This project was formally incorporated into a separate company named American Telephone and Telegraph Company on March 3, 1885. Starting from New York, the network reached Chicago in 1892. Bell's patent on the telephone expired in 1893, but the company's much larger customer base made its service much more valuable than alternatives and substantial growth continued. On December 30, 1899, the American Telephone and Telegraph Company bought the assets of American Bell; this was because Massachusetts corporate laws (which limited market capitalization to ten million dollars, preventing the direct growth of American Bell itself) were more restrictive than those of New York, where AT&T was headquartered. With this transfer of assets, AT&T became the parent of the Bell System. By 1902, there were 1,317,000 telephones under AT&T. National long-distance service reached San Francisco with the First transcontinental telephone call in 1915. This connection used a system of lines with loading coils and the Audion vacuum tube repeater first tested between New York and Philadelphia in 1913. Transatlantic services started in 1927 using two-way radio, but the first trans-Atlantic telephone cable did not arrive until Sept. 25, 1956, with TAT-1.

Monopoly

As a result of a combination of regulatory actions by government and actions by AT&T, the firm eventually gained what most regard as monopoly status. In 1907, AT&T president Theodore Vail made it known that he was pursuing a goal of "One Policy, One System, Universal Service." AT&T began purchasing competitors, which attracted the attention of antitrust regulators. To avoid antitrust action, in a deal with the government, Vail agreed to the Kingsbury Commitment of 1913. One of the three terms of the agreement forbade AT&T from acquiring any more independent phone companies without the approval of the Interstate Commerce Commission.

Worked examples

Example 1 — a first encounter with History of AT&T

Start with the simplest possible case. Write down what History of AT&T claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to History of AT&T before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about History of AT&T ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of History of AT&T

In research
History of AT&T appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses History of AT&T in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
History of AT&T is common in secondary-school and first-year university syllabi. It links to neighbouring topics AT&T, Bell System, History of companies of the United States, so understanding it makes those chapters shorter.
In everyday life
Look for History of AT&T outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
