High tech television functionalities

There was an item in the news about the global footprint of Belgians and the environmental awareness etc... They interviewed random people on the street about what we can do to help the environment and reduce our footprint.

"oh yes we can do a lot. We have e.g. just bought a new tv where you can turn off the image so you only have the sound...."


HUH????
Isn't that called 'a radio'?
