CBS

CBS (an initialism of the network's former name, the Columbia Broadcasting System) is an American commercial broadcast television network that is the flagship properties of CBS Corporation. The company is headquartered at the CBS Building in New York City with major production facilities and operations in New York City (at the CBS Broadcast Center) and Los Angeles (at CBS Television City and the CBS Studio Center).

CBS is sometimes referred to as the "Eye Network", in reference to the company's iconic logo, in use since 1951. It has also been called the "Tiffany Network", alluding to the perceived high quality of CBS programming during the tenure of its founder William S. Paley. It can also refer to some of CBS's first demonstrations of color television, which were held in a former Tiffany & Co. building in New York City in 1950.

The network has its origins in United Independent Broadcasters Inc., a collection of 16 radio stations that was purchased by Paley in 1928 and renamed the Columbia Broadcasting System. Under Paley's guidance, CBS would first become one of the largest radio networks in the United States, and eventually one of the Big Three American broadcast television networks. In 1974, CBS dropped its former full name and became known simply as CBS, Inc. The Westinghouse Electric Corporation acquired the network in 1995, renamed its corporate entity to the current CBS Broadcasting, Inc. in 1997, and eventually adopted the name of the company it had acquired to become CBS Corporation. In 2000, CBS came under the control of Viacom, which was formed as a spin-off of CBS in 1971. In late 2005, Viacom split itself into two separate companies, and re-established CBS Corporation – through the spin-off of its broadcast television, radio and select cable television and non-broadcasting assets – with the CBS television network at its core. CBS Corporation is controlled by Sumner Redstone through National Amusements, which also controls the current Viacom.

Radio

Radio is the use of radio waves is to carry information, such as sound, by systematically modulating some property of electromagnetic energy waves transmitted through space, such as their amplitude, frequency, phase, or pulse width. When radio waves strike an electrical conductor, the oscillating fields induce an alternating current in the conductor. The information in the waves can be extracted and transformed back into its original form.

Radio systems need a transmitter to modulate (change) some property of the energy produced to impress a signal on it, for example using amplitude modulation or angle modulation (which can be frequency modulation or phase modulation). Radio systems also need an antenna to convert electric currents into radio waves, and vice versa. An antenna can be used for both transmitting and receiving. The electrical resonance of tuned circuits in radios allow individual stations to be selected. The electromagnetic wave is intercepted by a tuned receiving antenna. A radio receiver receives its input from an antenna and converts it into a form usable for the consumer, such as sound, pictures, digital data, measurement values, navigational positions, etc. Radio frequencies occupy the range from a 3 kHz to 300 GHz, although commercially important uses of radio use only a small part of this spectrum.

Ronald Reagan

Ronald Wilson Reagan (/ˈrɒnəld ˈwɪlsən ˈreɪɡən/; February 6, 1911 – June 5, 2004) was an American politician and actor, who served as the 40th President of the United States from 1981 to 1989. Prior to his presidency, he served as the 33rd Governor of California from 1967 to 1975, following a career as a Hollywood actor and union leader.

Raised in a poor family in small towns of Northern Illinois, Ronald Reagan graduated from Eureka College in 1932 and worked as a sports announcer on several regional radio stations. After moving to Hollywood in 1937, he became an actor and starred in a few major productions. Reagan was twice elected as President of the Screen Actors Guild, the labor union for actors, where he worked to root out Communist influence. In the 1950s, he moved into television and was a motivational speaker at General Electric factories. Having been a lifelong liberal Democrat, his views changed. He became a conservative and in 1962 switched to the Republican Party. In 1964, Reagan's speech, "A Time for Choosing," in support of Barry Goldwater's floundering presidential campaign, earned him national attention as a new conservative spokesman. Building a network of supporters, he was elected Governor of California in 1966. As governor, Reagan raised taxes, turned a state budget deficit to a surplus, challenged the protesters at the University of California, ordered National Guard troops in during a period of protest movements in 1969, and was re-elected in 1970. He twice ran unsuccessfully for the Republican nominations in 1968 and 1976; four years later, he easily won the nomination outright, going on to be elected the oldest President, defeating incumbent Jimmy Carter in 1980.
