History of Radio
The history of radio is the history of technology that produced radio instruments that use radio waves. Within the timeline of radio, many people contributed theory and inventions in what became radio. Radio development began as "wireless telegraphy". Later radio history increasingly involves matters of programming and content.
The Marconi Company was a company that existed between 1897 until 2006. The company, founded by Guglielmo Marconi was originally known as The Wireless Telegraph & Signal Company.
The company opened the world's first radio factory on Hall Street in Chelmsford in 1898 and was responsible for some of the most important advances in radio and television
In 1939 the Marconi Research Laborotories at Great Baddow were founded and in 1941 there was a buy out of Marconi-Ekco Instruments to form Marconi Instruments.
The BBC launched DAB digital radio in 1995, and now offers eleven UK-wide digital radio stations (including five only available nationally on digital, and the World Service).
Since then, commercial operators have also made significant investments in digital radio. A national commercial multiplex licence was awarded to Digital One in 1998. Digital One launched its first national commercial services in 1999 and now offers eight services, including five available only on digital. Local DAB commercial services are now available from 46 local DAB digital radio multiplexes around the UK. Digital versions of the relevant BBC Local Radio or national services are also carried on the appropriate local commercial multiplex.
