 There have been several prior "waves" of 3D movie distribution, most notably in the 1950s when they were promoted as a way to offer audiences something that they could not see at home on television.Still the process faded quickly and as yet has never been more than a periodic novelty in movie presentation.The "golden era" of 3D film began in the early 1950s with the release of the first color stereoscopic feature, "Bwana Devil".
