3D episodes

There have been several notable examples in television where 3D episodes have been produced, typically as one hour specials or special events. Perhaps the best example of groundbreaking 3D production on television was the sitcom 3rd Rock From The Sun, which peaked in international popularity when it produced the two-part episode, Nightmare On Dick Street, where several of the characters' dreams are shown in 3D. The episode cued its viewers to put on their 3D glasses by including "3D on" and "3D off" icons in the corner of the screen as a way to alert them as to when the 3D sequences would start and finish. The episode is considered by some to be the show's magnum opus as it combined clever uses of metaphor with the character comedy and light moments of drama. It perhaps remains one of the show's most popular and memorable episodes.
