He was the father of the future…electric lights, power systems, motion pictures, recorded sound–even the tattoo pen. Life as we know it would be inconceivable without the prodigious output of the Wizard of Menlo Park, Thomas Alva Edison. His intense focus on his work came with a hefty personal price, but his reward was a world forever changed by his genius. Years after his death, Edison's effect is seen, heard, and felt everywhere. We follow descendants of his motion-picture camera to the tops of Earth's highest mountains, to the bottoms of its deepest oceans, and even into outer space. We track his innovations in recorded sound to CDs, iPods, sophisticated movie sound, and satellite radio. And we illuminate his world of electric light, powering the world and turning night into day. Along the way, we discover a little Edison in corners of modern life less well-known and even look at his failures. From the Internet to the stock market to pay-per-view; the Wizard is everywhere.
