...that Robert Adler has the dubious distinction of being the Father of the Couch Potato? Back in 1955 Adler was employed by what was then Zenith Radio Corp., where he was charged to invent something that would allow viewers to turn down the TV volume without leaving their chairs. After a series of flops (such as a wired contraption that people tripped over), Adler hit on the idea of using sound waves. Thus the Remote Control was born...
