History

The first airing of a remote broadcast came in 1924, when Loew's Theater publicist and WHN (New York City) station manager Nils Granlund leased telegraph lines from

to provide the first link in what became called cabaret broadcasting." By early 1925, Granlund had established remote lines between WHN and more than thirty New York City jazz nightclubs, including the Silver Slipper, The Parody Club, the
Cotton Club The Cotton Club was a New York City nightclub from 1923 to 1940. It was located on 142nd Street and Lenox Avenue (1923–1936), then briefly in the midtown Theater District (1936–1940).Elizabeth Winter"Cotton Club of Harlem (1923- )" Blac ...
, the Strand Roof, and Club Moritz. These big band remotes would become a staple of the old-time radio era, lasting well into the 1950s. Nils T. Granlund cited the 1925 WHN airing of Senator James J. Walker's announcement of his New York City mayoral candidacy through a remote broadcast from the New York Press Club as the first such remote link for a political forum. In Latin America on 27 October 1920, Dr Sussini made the first remote transmission in Argentina from the theatre El Coliseo in Buenos Aires. In Mexico on 27 September 1921, Adolfo Gomez Fernandez made a transmission from the Teatro Ideal, Mexico DF The very first live remote broadcast to the nation was by the Canadian Broadcasting Corporation in 1938 when Frank Willis reported on the Moose River Gold Mine disaster in Nova Scotia http://archives.cbc.ca/economy_business/natural_resources/clips/3860/ On 11 June 1955, NBC, The National Broadcasting Company, provided the 1st live remote broadcast to the nation from Niagara Falls, New York.Buffalo Evening News, Buffalo, NY, 11 June 1955

, remotes are often used for special events, such as concerts or sporting events, where either the entire event or advertisements for the event are broadcast on location. The cost of personnel and equipment is usually paid for by the host at each performance. However, if the event is recurring, such as a weekly broadcast from a

, then dedicated lines are usually installed by the local telephone company in order to save on costs. With low range radio stations, and at events with no telephone lines, several radio stations will call into the studio request line with a cell phone and microphone setup. From there, another DJ in the studio will put them on-location live on the air via the studio request line. Some stations use this method when doing live broadcasts in areas where the signal is weak.
