Communication

From the earliest times, people have found ways to communicate over long distances. Today, the technology of telecommunications lies at the heart of all modern communications networks. This book examines the history of communications from smoke signals to satellite signals and from telegrams to text messages, the development of mass communications, from print media to broadcast media, the impact of radio, television, and the Internet, the technology that links the world by cell phones and computers, and telecommunications of the future. This book goes beyond the science to explore the pros and cons of each new development, and examine the ways modern communications have changed society and the world.
