Inventor has switched off.
Robert Adler, who designed the couch potato device with the help of engineer Eugene Polley, died of heart failure on Thursday.
He was 93 years old and had been living in a nursing home in Idaho, USA.
Adler was a prolific inventor, earning more than 180 patents.
But he remained best known for his 1956 Zenith Space Command remote control, which helped make TV a truly sedentary pastime.
