In 1934, an EMI research team led by Sir Isaac Shoenberg developed the electronic Marconi-EMI system for television broadcasting, which replaced Baird's electro-mechanical system following its introduction in 1936. After the Second World War, EMI resumed its involvement in broadcast equipment production, providing the BBC's second television transmitter at Sutton Coldfield. It also manufactured broadcast television cameras for British television production companies and the BBC. The commercial television ITV companies also used them alongside cameras made by Pye and Marconi. Their most commercially successful piece of equipment was the EMI 2001 colour television camera, which was widely used in the British television industry from the end of the 1960s until the early 1990s. Exports of this piece of equipment were low, however, and EMI left this area of product manufacture.
EMI engineer Alan Blumlein received a patent for the invention of stereophonic sound in 1931. He was killed in 1942 whilst conducting flight trials on an experimental H2S radar set.
During and after World War II, the EMI Laboratories in Hayes, Hillingdon developed radar equipment (including the receiver section of the British Army's GL-II anti-aircraft fire-control radar), microwave devices such as the reflex klystron oscillator (having played a crucial role in the development of early production types following on from the British Admiralty Signal School's pioneering NR89, the so-called "Sutton tube"), electro-optic devices such as infra-red image converters, and eventually guided missiles employing analogue computers.
For many years, the company was internationally respected as a photomultiplier manufacturer. This part of the business was transferred to Thorn as part of Thorn-EMI, then later became the independent concern Electron Tubes Ltd.

Computers and CT scanner
The EMI Electronic Business Machine, a valve and magnetic drum memory computer, was built in the 1950s to process the British Motor Corporation payroll.
In 1958, the EMIDEC 1100, the UK's first commercially available all-transistor computer, was developed at EMI's Central Research Laboratories in Hayes under the leadership of Godfrey Hounsfield, an electrical engineer at EMI.
In the early 1970s, with financial support by the UK Department of Health and Social Security as well as EMI research investment, Hounsfield developed the first CT scanner, a device which revolutionised medical imaging. In 1973, EMI was awarded a prestigious Queen's Award for Technological Innovation for what was then called the EMI scanner; in 1979, Hounsfield won the Nobel Prize for his accomplishment.
After brief success in the medical imaging field, EMI's manufacturing activities were sold off to other companies, such as Thorn (see Thorn EMI). Subsequently, development and manufacturing activities were sold off to other companies and work relocated.
Emihus
Emihus Electronics, based in Glenrothes, Scotland, was owned 51% by Hughes Aircraft, of California, US, and 49% by EMI. It manufactured integrated circuits, electrolytic capacitors and, for a short period in the mid-1970s, hand-held calculators under the Gemini name.
Operations
Entertainment and leisure
In 1964, EMI acquired Blackpool Tower from the Bickerstaffe family. In 1967, it also took over the Winter Gardens complex in Blackpool.
In 1967, EMI acquired the Grade Organisation, the UK's largest showbusiness talent agency, for £7.5 million. This also included the recently acquired Shipman and King chain of 32 cinemas in the Home Counties.
Film, theatre and television
EMI Films was created in 1969 following the acquisition of Associated British Picture Corporation (ABPC). At the time ABPC owned 270 ABC Cinemas; a half share (under the Associated British Corporation name) in the ITV contractor Thames Television; Elstree Studios at Shenley Road, and had recently bought Anglo-Amalgamated, a film studio. Bernard Delfont of the Grade Organisation became chairman and Chief Executive. In 1970, Delfont sold his own Bernard Delfont Organisation to EMI and the agencies were divested. He later became Chief Executive of EMI in 1979.
Their flagship cinema was the ABC 1 and 2 Shaftesbury Avenue which was built at the old Saville Theatre in London.
In 1974, the Film & Theatre Corporation was split into EMI Cinemas and EMI Leisure Enterprises. On formation, EMI Cinemas ran 272 cinemas in the UK, including those of ABC.
Following EMI's merger with Thorn Electrical Industries in 1979, EMI's film division was renamed Thorn EMI Screen Entertainment. In April 1986, Thorn EMI sold its film production and distribution arm (Thorn EMI Screen Entertainment), home video (Thorn EMI Video), and cinema (ABC Cinemas) operations to businessman Alan Bond. Bond, in turn, sold it to The Cannon Group a week later.
EMI Leisure
EMI Leisure Enterprises was formed in April 1974 and controlled Blackpool Tower; EMI's 16 squash clubs and five bowling alleys; discotheques; 23 licensed premises and other amusement interests. It began developing new leisure businesses, including Brighton Marina and golf activities with the opening of Aldenham Golf Club. In April 1977 it acquired the Empire Ballroom and Cinema in Leicester Square in London and in September 1977 acquired Bailey Leisure Services Limited which it renamed EMI Dancing which provided the group with dance halls, cabaret clubs and discotheques around the UK. By the late 1970s, the leisure business contributed 15% of group revenues. In 1978, EMI acquired the Prince Edward Theatre. It also owned two other theatres in London as well as theatres in the rest of the UK.
Following the merger with Thorn, part of EMI's leisure interests were sold to Trust House Forte in November 1980 for £16 million. Lord Delfont became chairman and chief executive of THF's leisure division. EMI Social Centres chain of bingo halls remained with Thorn EMI.
The Winter Gardens in Blackpool were sold in 1983 to First Leisure.
Hotels and restaurants
In 1972, EMI Hotels won a bidding war against Ralston Purina to buy the Golden Egg group from the Kaye brothers for £14 million, which included a stake in Angus Steakhouse restaurants and the Selfridge Hotel, which opened in July 1973.
In June 1977, EMI acquired the Tower Hotel, London. At the end of 1978, they owned four other hotels: Royal Horseguards Hotel; Royal Angus; Royal Trafalgar; and Royal Westminster.
As well as Angus Steakhouse, their restaurants also included Wimpy Bars, Picnic Basket and Tennessee Pancake Houses.
Following the merger with Thorn, seven hotels and 12 Angus Steakhouse restaurants were sold in July 1980 for £23 million to Scottish & Newcastle Breweries.
EMI Music Publishing
As well as the well-known record label the group also owned EMI Music Publishing, which was the largest music publisher in the world. EMI Music Publishing has won the Music Week Award for Publisher of the Year every year for over 10 years; in 2009, for the first time in history the award was shared jointly with Universal Music Publishing. The publishing arm and record label are separate businesses.
EMI administered the publishing rights of over 1.3 million songs, headlined by Queen, Carole King, The Police, the Motown catalog, Kanye West, Alicia Keys, Drake, Sia, P!nk, Pharrell Williams, and Calvin Harris.
EMI's music publishing operations were sold to a consortium led by Sony/ATV Music Publishing in 2012; BMG acquired the music publishing libraries of Virgin Music (which EMI held) and Famous Music UK (which Sony/ATV held).
