Telegraph is the answer I would suggest, as that was the first invention that greatly accelerated the speed of communication. Following that came the telephone, and then after that, cell phones and the Internet. All of these communication tools have accelerated the rate and amount of global communication. But the first step in that direction was the telegraph.
