Introduction
Telephone was first introduced to Americans in 1876. It ushered US in a new era of communication, commerce, and social interaction. It started with the invention of telegraph and then, a brilliant mistake by Graham Bell, led to one of the greatest inventions for mankind.

Dawn of Telecommunication
• • • • • • • • Started around 1830 with introduction of telegraph machines which allowed quick and comprehensible communication across long distance. Telegraphs were the first instance of use of electromagnetism which helped usher in the era of electricity. Around 1850, America had around 23000 miles of telegraph lines, more than nations railroad tracks. In 1860, consolidation of telegraph industry happened. Western Union and American telegraph company emerged as the leaders. Consolidation killed the courier services, which were done on Pony. Associated press utilized the power of telegraph to become nations first telegraphic news company In 1866, transatlantic telegraph cables were laid between US and England. Graham bell arrives to US from Scotland in 1871, he in due time took telegraphic communication to the next level.

Bell’s Harmonic Telegraph
• Bell learnt about electricity after reading the book of a German scientist Helmholtz, who produced vowel sounds using electrified tuning forks. Book was in German, hence bell misinterpreted the text, he thought Helmholtz has successfully transmitted sounds over telegraph lines. Here Bell got the idea. Bell tried unsuccessfully Helmholtz’s idea, hence began creating and testing his own theories. Bell started working on Harmonic telegraph, which can send and receive multiple messages at the same time. Idea was to have a pair of tuning fork at both sender and receiver end and each fork will pick up the message sent by its pair at the opposite end. This will help in messages not getting mixed up. Bell rejected the idea of someone uttering words at sender end, which will travel as current to receiver end where harp would vibrate to produce speakers message in musical tones.











A Neck- to- Neck Race
• Studying Human Ear, Bell found that a tiny membrane could accurately reproduce the sound, which led him to think that why couldn’t the human voice also be transmitted and received over electrical wires? • Bell hired Thomas A. Watson as his full time assistant to help him in experimenting his ideas. • Another company Western Electric Company was also working on similar idea, so the first to patent the telephone idea will get the profits for patent period. • Well Known scientist Joseph Henry suggested that instead of Harmonic Telegraph Bell should focus on Telephone, which was strongly opposed by investors funding Bell. • But Bell continued to focus on Telephone instead of Harmonic Telegraph.

• Finally on March 10, 1876, Bell and Watson were able to successfully create the first prototype of the working telephone and became the inventor of this innovative new technology.

A Cloud of Suspicion
• Bell filed for patent of Harmonic Telegraph and Telephone on Feb 14, 1876. But major focus in the patent was on Harmonic Telegraph. • On the same day old time rival Elisha Gray of Western electric company too filed a caveat for telegraphic machine on the same day in patent office. • But patent office gave exclusive right of patent to Bell. The reason for the same was not cleared by patent office. People anticipated it to be because of Bell’s powerful friends financial backers. • It is also said that Bell actually stole the idea of Telephone from Elisha Gray.

• Award of patent followed decade’s worth of court proceedings and more than 600 lawsuits.
• But Bell made working telephone device before than Elisha Gray. Thus in the eyes of history, Alexander Graham Bell— with the help of his assistant, Thomas A. Watson— was, is, and will remain the inventor of the telephone.

THE INTERNATIONAL CENTENNIAL EXPOSITION
• Alexander Graham Bell was awarded his patent for the telephone on March 7, 1876. Then Bell and his team of investors started on the process of introducing telephone to America. A great opportunity to achieve this was the International Centennial Exposition, an international fair hosted by Philadelphia that included some of the day’s greatest scientific luminaries, such as Lord Kelvin and Joseph Henry. Although the scientific experts and dignitaries who witnessed Bell’s demonstration of his telephone that day were overwhelmed with wonder for this “talking telegraph,” many ordinary people who tried it out throughout the Centennial’s summer- long exhibit were less impressed. The device used was Bell’s magneto transmitter. The vast majority of Americans could not wrap their minds around the paradigm shift that a telephone conversation represented. Making improvements in the telephone technology, very first telephone call in history was conveyed over outdoor wires.

Bell Telephone Company
• In Feb 1877, Bell’s invention became more secure when Bell was issued a second patent for operations of the telephone. • On July 9,1877 Bell Telephone Company was formed. • Bell had a dream of wiring entire America with telephone lines, but the company was severely cash strapped. • As demand outstripped supply, the making of equipment and establishment and maintenance of phone services had to be outsourced. • Company started leasing out equipment instead of one time sale that enabled steady stream of income as the customers started viewing phone service as a benefit to them. This was a masterstroke.

Creating a Monopoly
• As Bell Telephone began to enjoy a modest success in late 1870s, it started facing problems due to economic depression and aggressive entrance into telephone business by Western Union. • The only way for Bell Telephone to survive and compete was to sue Western Union for patent infringement, which it did in September 1878. This put even more pressure on the already cash strapped company. • Company decided to reorganize to capitalize on its current strengths and expand its influence beyond its solid core. Company split into 2 companies: the New England Telephone Company and a new Bell Telephone Company. • Theodore N Vail was hired as general manager to ensure company’s survival but also its growth into a dominant corporation and an industry monopoly.

Building a National Network
• Vail focussed on two primary aspects: aggressively fight Western Union’s patent infringement , beat it on the technology front and focus on research and development. He also sought to raise the courage and spirits of Bell Telephone’s field agents, who were trying to establish competing telephone exchanges nationwide. •



New England Telephone and Bell Telephone were reunited and rechristened the National Bell Telephone Company to raise desperately needed funds and ward off threat from Western Union.
Meanwhile Western Union itself faced the threat of being taken over by a rival telegraph company and conceded defeat. This allowed Bell Telephone to expand and flourish. Within 2 years of settlement with Western Union, the company began to turn a profit. Rather than complacently enjoying its current sole possession of the telephone field, Vail was determined that Bell Telephone had to plan for the day when it would not be alone in the effort to wire America. Vail’s overarching visionary goal was to create a unified national phone network based on the advent of strong and reliable long- distance, coast- to- coast service. This was in sync with Bell’s dream to wire entire America.







Building a National Network Contd.
• To achieve his vision, he focused on upgrading the telephone equipment, manufacturing, and infrastructure to improve service, reliability, and sound quality; extending telephone service to as much remaining “virgin territory” (localities not yet wired for telephone service) as possible; & consolidating the quasi- independent local service providers under Bell’s control and influence. The equipment had evolved from Watson’s earlier one- piece magnetotransmitter/ receiver into a three- piece, wall- mounted apparatus. Telephone circuits were changed from one wire to metallic circuits to copper ones that greatly improved sound quality. Bell Telephone acquired the Western Electric Manufacturing Company and it became the sole supplier of equipment to its parent company. AT&T was born that was dedicated exclusively to the building and operating of long- distance phone lines. It helped expand Bell’s territory and increased control over local service providers since they needed a license from Bell with rights to get into the telephone business.

The Industry Transformed
• In 1969, on account of frequent service breakdowns (because of maxed out system capacity and poorly maintained telephony infrastructure), the Govt. opened the market by allowing entry of independent players like Sprint, MCI, which became threats to AT&T within next few years. The Govt. also allowed GTE (telephone manufacturers independent of AT&T) to make and sell phone equipment to AT&T/Bell customers that would be compatible with the Bell network. Meanwhile, Bell Labs began to develop Fibre-optic cables for digitized communication but AT&T could not capitalize on it. Consequent to the settlement of its lawsuit with the Govt., AT&T was diminished radically as it had to give up 22 regional Bells, which reorganized to become seven independent telephony companies. AT&T’s assets fell from $150 billion to $34 billion! Sprint established an all-fibre-optic phone network in 1987 – 2 years before AT&T announced its intention to replace its microwave and coaxial cable network with fibre-optic cables. AT&T established the first cellular phone system in USA in 1983, which sowed the seeds of mobile telephony revolution in the 21st century.







The Industry Transformed Contd...
• The cellular phone market attracted many more players and became a highly competitive one. Sprint and Verizon offered stiff competition in the local and long distance markets as well as the cellular market. T-Mobile, Alltel, Cingular, Nextel were the other service providers. Phone manufacturing market was now crowded by Sony, Panasonic, GE, Nokia, LG, Motorola, Samsung, Siemens, BlackBerry, etc. After several rounds of restructuring, AT&T finally emerged as three distinct companies in 2000. One company focused on cellular telephony; the second focused on broadband, internet and cable television; and the third remained as AT&T and focused on local and long-distance telephony. In 2005, AT&T agreed to be purchased by SBC Communications (the former Southwestern Bell) for $16 billion. But, then, SBC rechristened itself as AT&T Inc. In 2007, AT&T became the exclusive carrier and distributer of iPhone. AT&T is still the largest communications company in the world. It offers cellular service to 70 million customers, and it remains the leading provider of longdistance and local wire- based phone service. It is the USA’s largest provider of broadband.
