Is your house divided whether to root for the Patriots or the Eagles?? Debating whether to watch the Super Bowl or the Puppy Bowl?? Maybe what you need is this television played two channels at once.? The DuMont Duoscopic Television was actually two televisions in the same cabinet, with mirrors and polarizers to combine the images. Viewers wore special Polaroid glasses and earpieces to cancel out the show they weren’t watching.
