Staged commercial photograph with models. This type of television played two different stations simultaneously because it was actually two televisions in the same cabinet, with mirrors and polarizers to combine the images. One station was visible and audible without special equipment (?); the second station required the Polaroid glasses and earpieces, so two programs could be viewed on one television by two different viewers or groups. While Polaroid glasses were generally used to combine two images in the viewers' minds, in this case the glasses were used to separate superimposed visual signals. The Duoscopic was never introduced to the consumer market because it was a "goofy idea," as some commentators have written--it was merely an alternative to buying two televisions.
