Polaroid Corporation a "juggernaut of innovation", in many respects Polaroid was the Apple of its time with a "leader in Edwin Land, a scientist who guided the company as the founding CEO for four decades". Polaroid’s initial market was in polarized sunglasses — spawned from Land’s self-guided research in light polarization. Land, having completed his freshman year at Harvard University, left to pursue this market, resulting in Polaroid's birth. Land later returned to Harvard to continue his research. Polaroid, owning patents to its polarizer technology, got its start by employing polarization in products that included 3-D movies and glare-reducing goggles for dogs.
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.
