Polaroid Corporation it had asked for. In 1977, Land introduced the Polaroid Instant Home Movie camera named Polavision, based on the Dufaycolor process. However, the product arrived on the market when videotape-based systems were rapidly gaining popularity. Thus it failed to sell well in retail stores and has been described as the swan song for Polaroid. After four decades as chairman, Edwin Land was coerced into resigning and leaving the corporation he had founded. He died in 1991. The "Polavision" debacle eventually caused the company to write off $89 million, including most of the manufactured products. The underlying technology of Polavision was
Instant camera integral instant film, similar to but incompatible with Polaroid's SX-70 film. The film was chemically similar to Polaroid's with the exception that the negative was exposed from the rear and the dye/developers diffused to the front of the photogragh. This alleviated the need for a mirror to reverse the image before it struck the negative. Even so, Polaroid brought a patent-infringement lawsuit against Kodak, and eventually Kodak was forced to stop manufacture of both the camera and film. Kodak was also left to pay a settlement to customers who were left without a way to use their now defunct cameras.
