I developed very slowly and it took nearly two hundred years before I was built as an analytical machine by Charles Babbage.

By the 1940s I had grown as large as a room, and I wondered if I would grow any larger. Over time my memory has developed so much that, like an elephant, I never forget anything I have been told! And my memory became so large that even I couldn’t believe it! But I was always so lonely standing there by myself, until in the early 1960s they gave me a family connected by a network. I am now truly filled with happiness that I am a devoted friend and helper of the human race!
