Yes, TV does use radio waves. Traditional broadcast TV signals are transmitted over the air through radio waves from a TV station's antenna to your TV. Modern digital TVs still use radio waves, but the signals are now digital rather than analog. These radio waves are converted into audio and video signals by your television.
