"So What?"/Legacy
Thomas Edison's inventions were created and constructed in the late 1800's, but most had their biggest impact in the 20th century. His inventions made the progress of technology something possible. Its hard to find someone who has not been affected by Edison's legacy. Almost anyone around the world has seen some type of film, or heard a recording of music. Lights turn on from the flick of a switch. Baseball fields light up like the 4th of July on nights. Police stop crime sometimes with the help of recording devices. Cinema movies almost look dangerously real now-a-days, especially in 3D! People who live in this day in age, in fact century, have had better and more enjoyable lives because of his inventions. And one of Edison's most important roles might not be his inventions in some cases but his imagination in all cases.
