In 1838, Samuel Morse invented the electric telegraph. It could send messages over long distances faster than traditional methods (horseback, word-of-mouth, etc..) by listening to a series of clicks. This made news travel faster and easier, and created specific jobs. The reason Samuel Morse created the telegraph was because his wife had died, and he didn't recieve news until weeks later.
