For most of human history, information traveled only as fast as a person or horse could carry it. That changed in the 19th century when the first telegraph message made near-instant communication over long distances possible. Soon afterward, Alexander Graham Bell patented the telephone and made the first telephone call, allowing people to speak across cities for the first time. Thomas Edison then introduced the phonograph, the first device capable of recording and playing back sound, and a few decades later the first public television demonstration added moving images to communication. This campaign reveals how a series of revolutionary inventions transformed the way people connect and laid the foundations of today's connected world.
