The calculating machines he invented in the 19th century, although never fully realised in his lifetime, are rightly seen as the forerunners of modern programmable computers. What if he had succeeded? Babbage already had plans for games arcades, chess playing machines, sound generators and desktop publishing. A Victorian computer revolution was entirely possible.
