Discover the behind-the-scenes stories of the inventors and inventions that primed the world for our current communications, media, and information explosion. ""Communications and Broadcasting, Revised Edition"" sets the scene with a look at the development and interconnection of scientific ideas: electromagnetism, leading to the telegraph and telephone; Maxwell's wave theory, leading to radio and television; and communications and information theory, from Claude Shannon to the World Wide Web and beyond. Then there are engaging portraits of the inventors themselves - visionaries who were part scientist, part engineer, and part entrepreneur. Students will find out how they made modern communications possible, and how they repeatedly recast its media.
