Online shopping was invented and pioneered by Michael Aldrich in the UK. In 1979 he connected a modified domestic television via a telephone line to a real- time multi-user transaction processing computer. He marketed the system from 1980 onwards and sold mainly Business-to-Business systems. The systems were installed in the UK, Ireland and Spain. There were a number of significant world firsts with new applications in holiday travel, vehicle and spares sales, loan finance, and credit ratings. These applications and others migrated to the internet in the 1990s although some of his systems were still in use in 2000.
