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.

Radio program

A radio program (radio programme in the United Kingdom) or radio show is a segment of content intended for broadcast on radio. It may be a one-time production or part of a periodically recurring series. A single program in a series is called an episode.

International radio

In Britain, radio broadcasting was dominated entirely by the BBC, which since the early 1920s had been developing a broad spectrum of programming including different genres of music and speech, including documentaries, drama, comedy, news, religious broadcasts, children's programmes, schools broadcasts and sports coverage). BBC output was a unifying force within British culture, and has been written about extensively elsewhere.

In the 1950s, a small but growing cohort of Rock and pop music fans, dissatisfied with the BBC's output, might listen to Radio Luxembourg, but to too small an extent to have any impact on the BBC's monopoly and invariably only at night, when the signal from Luxembourg was stronger. During the post-1964 period, western Europe offshore radio (such as Radio Caroline broadcasting from ships at anchor or abandoned forts) helped to supply the demand for the pop and rock music. The BBC launched its own pop music station, BBC Radio 1, in 1967.

Laura Ingraham

Laura Anne Ingraham (born June 19, 1963) is an American radio talk show host, best-selling author, and conservative political commentator. Her nationally syndicated talk show, The Laura Ingraham Show, airs throughout the United States on Courtside Entertainment. Ingraham is also the official guest host for Fox News Channel's The O'Reilly Factor and a contributor for This Week on ABC News.

Early life and career

Ingraham grew up in a middle-class family in Glastonbury, Connecticut, where she was born to Anne Caroline (née Kozak) and James Frederick Ingraham III. Her maternal grandparents were Polish immigrants. She graduated from Glastonbury High School in 1981.

Ingraham earned a Bachelor of Arts at Dartmouth College in 1985 and a Juris Doctor at the University of Virginia School of Law in 1991. As a Dartmouth undergraduate, she was a staff member of the independent conservative newspaper, The Dartmouth Review. In her senior year, she was the newspaper's editor-in-chief, its first female editor. She wrote several controversial articles during her tenure, notably an article alleging racist and unprofessional behavior by Dartmouth music professor Bill Cole, who later sued Ingraham for $2.4 million. The college paid his legal costs. The suit was settled in 1985.Jeffrey Hart, the faculty adviser for The Dartmouth Review described Ingraham as having "the most extreme anti-homosexual views imaginable", claiming "she went so far as to avoid a local eatery where she feared the waiters were homosexual." In 1997, she wrote an essay in the Washington Post in which she stated that she changed her views on homosexuality after witnessing "the dignity, fidelity and courage" with which her gay brother Curtis and his companion coped with AIDS. Ingraham has stated that she supports civil unions, but still believes that marriage "is between a man and a woman".
