There was a time when if you wanted to know a phone number you had to manually consult a huge book, if you wanted to share a photo with family you had to manually carry the print to them, if you wanted to watch a movie at home you had to drive to blockbuster, and if you wanted to hurl abuse at a politician you had to wait for them to hold a rally in your city and queue for hours to get a front row seat.

Now I can find phone numbers, share photos with family, watch movies on demand and hurl abuse at politicians, all without leaving my chair.
