In 1979, Michael Aldrich connected a modified television to a computer through a domestic telephone line. The arrangement let people use a menu-driven screen to exchange information and make transactions with businesses in real time. Before the internet and the World Wide Web became everyday tools, Aldrich had conceived and built a working form of online shopping. He went on to develop systems for companies, devise a home computer-and-television hybrid and advise on the future of information technology in Britain.
From Hull to the computer industry
Michael John Aldrich was born in Welwyn Garden City, Hertfordshire, on 22 August 1941. He attended Clapham College in London and, in 1959, won a scholarship to the University of Hull to study history. He married Sandy Kay Hutchings, whom he had met while she was a student at Hull Art College, in 1962. They had four children.
Aldrich spent 15 years in sales and marketing roles at Honeywell and Burroughs before joining the board of Redifon in 1977. He would spend much of his working life in the computer industry, including 20 years as chief executive of Redifon and its successor businesses. His experience in commercial computing helped bring the practical demands of business together with his interest in making information systems accessible beyond the organisations that owned them.
A television becomes a shopping terminal
Aldrich’s 1979 system used a modified domestic television, connected by telephone line to a real-time transaction-processing computer. Its interface drew on videotex: a simple, menu-led way to present and retrieve information. Aldrich saw the medium as more than a shop window. It could connect customers, suppliers and other outside users to corporate information systems, allowing transactions, messages and information exchange.
In March 1980, Redifon launched what Aldrich called Office Revolution. The idea was to open business computer systems to consumers, customers, agents, distributors, suppliers and service companies, so that business could be conducted electronically in real time. During the 1980s, Aldrich and his team designed, made, sold, installed and supported online shopping systems using videotex. These pre-dated the internet and the World Wide Web, and were used mainly by large companies in Britain.
The systems reached into several industries. Thomson Holidays had a business-to-business online shopping system in 1981. In 1984, a Gateshead service linked local shoppers with Tesco; the first recorded online home shopper was 72-year-old Jane Snowball. Aldrich’s systems also served car businesses: Ford used a network to help dealers locate and obtain vehicles, while Nissan combined dealer purchasing with consumer sales and finance checks. These examples show how the underlying idea could handle more than a simple order: it could link information, credit and purchasing across a business network.
Other projects applied computing to large administrative tasks. A 1978 system read hand-printed railway timesheets to support the weekly payroll for British Rail’s workforce. In 1981–83, Aldrich’s company worked on a network for the Siberian gas pipeline, involving 46 computer systems, 1,200 terminals and 240 Teleputers. The same period saw a Ford Europe network and a system to price more than 334 million medical prescriptions a year for the Prescription Pricing Authority. Later work included a cattle-passport system for the British Cattle Movement Service during the BSE crisis.
The Teleputer and the wired home
In 1980, Aldrich developed the Teleputer, combining a television with computing and telecommunications. Its prototype used a modified 14-inch colour television and a separate unit containing a Zilog Z80 microprocessor. It could operate as a personal computer, run applications and connect to other computers over dial-up or leased lines. The equipment included a keyboard, printer and floppy disks; a hard disk was added later.
Aldrich had imagined the Teleputer for homes, as part of a broader vision of connected services and interactive broadband cable television. A consumer market was not ready for it, so the system went into business use without its television tuner. It was used in Britain and, in a Cyrillic version, in the then Soviet Union. Aldrich’s interest in connected homes also informed his campaign for cable technology. His proposals for local-loop broadband, delivered alongside television and telephone services, formed part of his work advising the British Government on information technology.
His contribution was not limited to shopping and home computing. Aldrich worked on large-scale data capture, mixed-media scanning, minicomputer networking, voice response and handprint processing. In 1984, he patented a static-signature recognition system. He also founded ROCC Computers in 1984 following a management buy-out of Rediffusion Computers; the company traded mainly in Britain and Eastern Europe.
Public service, institutions and recognition
From 1981 to 1986, Aldrich served on the Government’s Information Technology Advisory Panel, a group of six experts that reported to Prime Minister Margaret Thatcher. The panel produced three published reports. Aldrich wrote a paper on recabling Britain with local-loop broadband and on financing the network by distributing television, data and telephone services together. The government subsequently changed the law to permit the new cable systems.
He also held professional and civic roles. He was president of the Institute of Information Scientists in 1984–85 and chairman of the Tavistock Institute of Human Relations from 1989 to 1999. His long association with the University of Brighton began through support for employees studying engineering and computer science. He served on its governing body for 17 years, including 11 as chairman, and later chaired its foundation. The university named its business, biosciences, engineering and technology library after him. He and Sandy Aldrich established a collection of contemporary art at the university, and he donated his IT papers from 1977 to 2000 for its archive.
Aldrich became a Fellow of the British Computer Society in 1984 and a Chartered Fellow in 2004. The University of Brighton awarded him an honorary Doctor of Letters in 2002. The existing account also records a Computer Weekly Lifetime Achievement Award in 2010. His archive continued to support teaching and research at Brighton, and the university established a prize for an outstanding e-commerce student in his name.
Why Michael Aldrich deserves a place in British Legacy
Aldrich’s British legacy rests on a specific, consequential achievement: he turned a domestic television and telephone line into a practical way to shop and transact with businesses. His 1979 system was not simply an early prediction about future technology. He and his team went on to design and install working services, from holiday bookings and supermarket shopping to car purchasing and finance. Their systems show how online transactions could connect customers and businesses before the web made such exchanges familiar. The British examples include the Gateshead service used by Jane Snowball and the complex networks built for retailers, manufacturers and public services.
His wider record matters too. Aldrich explored how computing might move out of corporate data centres and become a medium for communication, information and participation. The Teleputer and his proposals for connected homes were expressions of that ambition; his government advisory work addressed how Britain might build the networks to support it. Alongside invention, he contributed to professional and educational institutions, including the University of Brighton, where his archive and the student prize attached to his name keep his work available for study. Remembering Aldrich therefore gives British Legacy a richer account of technological change: one grounded not only in a celebrated idea, but in systems built, public service undertaken and institutions strengthened.
