Reseña del editor

While Alexander Graham Bell won the race to patent the telephone, he was only one among many inventors who explored instant voice communication. This fascinating book describes the evolution of the telephone from the invention of the telegraph by Marconi to the modern day cell phones that have become a popular part of our everyday life. It also takes a close up look at how the telephone works, early inventors, those who continue to enhance the technology, and telephone companies, their products, and competition.Describes why and how the telephone was invented, how the telephone system was developed, and how the telephone has been physically improved since its invention.
