In the early 1900s, Philo T. Farnsworth and Vladimir Zworykin were each separately working on ideas to send pictures using radio signals and vacuum tubes. The result of their work was the television, a device that would change the way people around the world receive news and entertainment. To this day, engineers continue to build upon Farnsworth and Zworykin's inventions, resulting in the smart TVs of today. In clear, concise language, this book explores the invention and evolution of the television.
