This is a good History of ICT clutch of URLs (timelines etc) http://www.shambles.net/pages/staff/icthistory/ For my money, the one real ICT that has impacted virtually everyone's day to day life and work (in the Western economies) is the old bog standard phone.
From being a relatively rare and (in the UK at least) only for use in emergencies and usually located in the coldest part of the house (ours at home in North London, in the '60s, was in the coast cupboard in the hallway - very typical) it became, via direct dial and long distance, a virtually ubiquitous means of organising and running our social, work, and economic lives - from chatting to my neighbour next door to friends 4000 miles away - almost without thinking.
