Apple's iPhones and iPads have led the era of consumerisation, but their adoption would not have been possible without the advent of the home computing era which began in earnest in the early 1980s.
Computing recently travelled to the Centre for Computing History in Cambridge to find out more.
This video is part of Computing's celebration of its 40th year - the brand was launched in 1973. Further events and videos will be shown at the UK IT Industry Awards on November 13th, at Battersea Park Events Arena.
Tickets, and tables are available here.
