Breakup of the Bell SystemW
Breakup of the Bell System

The breakup of the Bell System was mandated on January 8, 1982, by an agreed consent decree providing that AT&T Corporation would, as had been initially proposed by AT&T, relinquish control of the Bell Operating Companies that had provided local telephone service in the United States and Canada up until that point. This effectively took the monopoly that was the Bell System and split it into entirely separate companies that would continue to provide telephone service. AT&T would continue to be a provider of long-distance service, while the now-independent Regional Bell Operating Companies (RBOCs), nicknamed the 'Baby Bells', would provide local service, and would no longer be directly supplied with equipment from AT&T subsidiary Western Electric.

Federal Communications Commission Consolidated Reporting Act of 2013W
Federal Communications Commission Consolidated Reporting Act of 2013

The Federal Communications Commission Consolidated Reporting Act of 2013 is a bill that passed the United States House of Representatives during the 113th United States Congress. The bill would "require the Federal Communications Commission (FCC) to prepare a biennial report for the Congress that assesses certain characteristics of the communications industry." That report would include an analysis of "the state of competition in the markets for voice, video, and data services, as well as the availability of high-speed and high-quality telecommunications services" in the United States. Perhaps most importantly, "the bill would require the FCC to determine whether laws and regulations pose a barrier to entry into communications markets and to include that information in the biennial report." The bill would also cancel a number of preexisting requirements for various other reports from the FCC.

Federal Radio CommissionW
Federal Radio Commission

The Federal Radio Commission (FRC) was a government agency that regulated United States radio communication from its creation in 1927 until 1934, when it was succeeded by the Federal Communications Commission (FCC). The FRC was established by the Radio Act of 1927, which replaced the Radio Act of 1912 after the earlier law was found to lack sufficient oversight provisions, especially for regulating broadcasting stations. In addition to increased regulatory powers, the FRC introduced the standard that, in order to receive a license, a radio station had to be shown to be "in the public interest, convenience, or necessity".

First transcontinental telephone callW
First transcontinental telephone call

A telephone call, which for marketing purposes is claimed to be the first transcontinental telephone call, occurred on January 25, 1915, a day timed to coincide with the Panama–Pacific International Exposition celebrations. However, the transcontinental telephone line was first completed on June 17, 1914, and successfully first voice tested in July 1914. A 1998 U.S. postage stamp commemorates the completion of the line in 1914.

Hush-A-Phone Corp. v. United StatesW
Hush-A-Phone Corp. v. United States

Hush-A-Phone v. United States, 238 F.2d 266 was a seminal ruling in United States telecommunications decided by the D.C. Circuit Court of Appeals. Hush-A-Phone Corporation marketed a small, cup-like device which mounted on the speaking party's microphone, reducing the risk of conversations being overheard and increasing sound fidelity for the listening party. At the time, AT&T had a near-monopoly on America's phone system, even controlling the equipment attached to its network. In this era, Americans had to lease equipment from Ma Bell or use approved devices. Hush-A-Phone had been around for 20 years without any issues. However, when an AT&T lawyer saw one in a store window, the company decided to sue on the grounds anything attached to a phone could damage its network.

Overland Telegraph CompanyW
Overland Telegraph Company

In 1860, the Pacific Telegraph Act of 1860 called for the facilitation of communication between the east and west coasts of the United States of America. Hiram Sibley of the Western Union Telegraph Company won the contract. In 1861, Benjamin Franklin Ficklin joined Hiram Sibley in helping to form the Pacific Telegraph Company of Nebraska. At the same time, Jeptha Wade was asked by Hiram Sibley to encourage the consolidation of telegraph companies in California, a process that had been underway there anyway, most notably involving the merger of the two largest intrastate companies following a lawsuit between them, the Alta Telegraph Company and the California State Telegraph Company. The Overland Telegraph Company of California was thus formed with Horace W. Carpentier of the California State Telegraph Company serving as its president, and it began building east from Carson City, Nevada while its eastern counterpart, the Pacific Telegraph Company began building west from Omaha, Nebraska. Upon their connection in Salt Lake City, Utah on October 24, 1861, the final link between the east and west coast of the United States of America was made. The First Transcontinental Telegraph led to the immediate demise of the Pony Express. The Pacific Telegraph Company of Nebraska and the Overland Telegraph Company of California were eventually absorbed into the Western Union Telegraph Company.
