Imagine the past… primitive computers, the size of a room, used exclusively by top companies, universities, or government agencies. No internet exists and nobody knows what ‘social media’ is supposed to be. To call somebody, you use a rotary-dial telephone attached to a socket in the wall. You have three or four TV stations, but they shut around midnight. To get your news, you purchase your favourite newspaper in print. To buy anything, you pay by cash or perhaps by cheque. If you are young and love music, you might carry a cassette Walkman around with you. And nobody can contact you if they don’t know where you are.
