Broadcasting is the distribution of audio and video content to a dispersed audience via any audio visual medium. Receiving parties may include the general public or a relatively large subset thereof. It has been used for purposes of private recreation, non-commercial exchange of messages, experimentation, self-training, and emergency communication such as amateur (ham) radio and amateur television (ATV) in addition to commercial purposes like popular radio or TV stations with advertisements.

The term broadcast was first adopted by early radio engineers from the Midwestern United States, treating broadcast sowing as a metaphor for the dispersal inherent in omnidirectional radio signals.Broadcasting is a very large and significant segment^[quantify] of the mass media.

Originally all broadcasting was composed of analog signals using analog transmission techniques and more recently broadcasters have switched to digital signals using digital transmission.

The world's technological capacity to receive information through one-way broadcast networks more than quadrupled during the two decades from 1986 to 2007, from 432 exabytes of (optimally compressed) information, to 1.9 zettabytes. This is the information equivalent of 55 newspapers per person per day in 1986, and 175 newspapers per person per day by 2007.

John Mayall, OBE (born 29 November 1933) is an English blues singer, songwriter, and multi-instrumentalist, whose musical career spans over fifty years. In the 1960s, he was the founder of John Mayall & the Bluesbreakers, a band which has included Eric Clapton, Jack Bruce, Peter Green, John McVie, Mick Fleetwood, Mick Taylor, Don "Sugarcane" Harris, Harvey Mandel, Larry Taylor, Aynsley Dunbar, Hughie Flint, Jon Hiseman, Dick Heckstall-Smith, Andy Fraser, Johnny Almond, Walter Trout, Coco Montoya and Buddy Whittington.

Mayall's father was Murray Mayall, a guitarist and jazz music enthusiast. From an early age, John was drawn to the sounds of American blues players such as Leadbelly, Albert Ammons, Pinetop Smith, and Eddie Lang, and taught himself to play the piano, guitars, and harmonica.

Mayall spent three years in Korea for national service and, during a period of leave, he bought his first electric guitar. Back in Manchester, he enrolled at Manchester College of Art (now part of Manchester Metropolitan University) and started playing with semi-professional bands. After graduation, he obtained a job as an art designer but continued to play with local musicians. In 1963, he opted for a full time musical career and moved to London. His previous craft would be put to good use in the designing of covers for many of his coming albums.

The word asshole, a variant of arsehole, which is still prevalent in British and Australian English, is a vulgar to describe the anus, often pejoratively used to refer to people.

The word arse in English derives from the Germanic root *arsaz, which originated from the Proto-Indo-European root *ors — meaning buttocks or backside. The combined form arsehole is first attested from 1500 in its literal use to refer to the anus. The metaphorical use of the word to refer to the worst place in a region, e.g., "the arsehole of the world") is first attested in print in 1865; the use to refer to a contemptible person is first attested in 1933. In the ninth chapter of his 1945 autobiography, Black Boy, Richard Wright quotes a snippet of verse that uses the term: "All these white folks dressed so fine / Their ass-holes smell just like mine ...". Its first appearance as an insult term in a newspaper indexed by Google News is in 1965. As with other vulgarities, these uses of the word may have been common in oral speech for some time before their first print appearances. By the 1970s, Hustler magazine featured people they did not like as "Asshole of the Month." In 1972, Jonathan Richman's Modern Lovers recorded his song "Pablo Picasso," which includes the line "Pablo Picasso was never called an asshole."

Richard P. "Richie" Havens (born January 21, 1941) is an African American folk singer and guitarist. He is best known for his intense, rhythmic guitar style (often in open tunings), soulful covers of pop and folk songs, and his opening performance at the 1969 Woodstock Festival.

Born in Brooklyn, Havens was the eldest of nine children. At an early age, he began organizing his neighborhood friends into street corner doo-wop groups and was performing with The McCrea Gospel Singers at 16. At age 20, Havens left Brooklyn, seeking artistic stimulation in Greenwich Village. "I saw the Village as a place to escape to, in order to express yourself," he recalls. "I had first gone there during the Beatnik days of the 1950s to perform poetry, then I drew portraits for two years and stayed up all night listening to folk music in the clubs. It took a while before I thought of picking up a guitar."^{[citation needed]}

Havens' reputation as a solo performer soon spread beyond the Village folk circles. After cutting 2 records for Douglas Records, Havens signed on with Bob Dylan's manager Albert Grossman, and landed a record deal with the Verve Forecast label. Verve released Mixed Bag in 1967, which featured tracks like "Handsome Johnny" (co-written by Havens and future Oscar-winning actor Louis Gossett Jr.), "Follow", and a cover of Bob Dylan's "Just Like a Woman". By 1969, he had released five more albums. Something Else Again (1968) became Havens' first album to hit the Billboard chart and also pulled Mixed Bag back onto the charts.

Eric Victor Burdon (born 11 May 1941) is an English singer-songwriter best known as a member and vocalist of rock band The Animals, and the funk rock band War and for his aggressive stage performance. He was ranked 57th in Rolling Stone's list - The 100 Greatest Singers of All Time.

Burdon was lead singer of The Animals, formed during 1962 in Newcastle, England. The original band was the Alan Price Combo which formed in 1958. They became the Animals shortly after Burdon joined the band. They combined electric blues with rock and in the USA were one of the leading bands of the British Invasion. Along with The Beatles, The Rolling Stones, The Dave Clark Five, and The Kinks, the group introduced British music and fashion. Burdon's powerful voice can be heard in The Animals singles "The House of the Rising Sun", "Sky Pilot", "Monterey", "I'm Crying", "Boom Boom", "Don't Let Me Be Misunderstood", "Bring It On Home to Me", "Baby Let Me Take You Home", "It's My Life", "We Gotta Get out of This Place", "Don't Bring Me Down", and "See See Rider".
