10 and 12 researched events on one shared scale. Canon 1933–present, Polaroid 1932–present.
The axis stretches where either maker has research and collapses where neither does, so a year sits opposite the same year on both. Event counts differ because research depth differs, not because one company did less.
Land and George Wheelwright built a Boston-area research company around synthetic polarizing sheet, moving from experimental rooms into purpose-built production. In 1937 new investment supported reincorporation as Polaroid Corporation and transferred the laboratory patents into the new firm.
The Invention of the Polarizer · Commercialization of the Polarizer
Goro Yoshida, Saburo Uchida, and Takeo Maeda established the Precision Optical Instruments Laboratory in Tokyo in November 1933 to develop a high-grade 35mm camera. The Kwanon was a prototype, not a regular commercial line. The Hansa Canon reached the market in February 1936 under a joint arrangement: Nippon Kogaku supplied the Nikkor lens, mount, viewfinder optics, and rangefinder mechanism, while Canon's predecessor made the body and shutter and assembled the camera.

The business was incorporated as Precision Optical Industry Co., Ltd. on 10 August 1937. It developed the Serenar lens and began moving toward internal optical production. Wartime disruption damaged facilities and constrained materials, but the company received permission on 1 October 1945 to resume camera manufacture. Canon's current corporate founding date refers to the 1937 incorporation, not the laboratory's 1933 beginning.

Military and industrial optical work expanded Polaroid beyond sunglasses and camera filters. The company learned to manufacture coated materials and precision optical assemblies at scale, creating the interdisciplinary base of chemistry, mechanics and design that later supported instant photographic systems.
Postwar cameras initially appeared with either Serenar or Nikkor standard lenses because materials and production were still unsettled. Canon expanded in-house Serenar manufacture, and Nippon Kogaku stopped supplying Nikkor lenses in 1948. Precision Optical Industry became Canon Camera Co., Inc. in 1947. Rangefinders supported export growth while Canon began to build capabilities in cine cameras, broadcast lenses, and business equipment.

Land demonstrated instant photography in 1947, and the Model 95 reached customers in 1948. Its negative-positive roll-film process used camera rollers to spread reagent before the photographer peeled apart a finished print, relocating much of the darkroom process into a portable system.

The Model 95 opened a broad family of folding roll-film cameras, followed by higher-specification 110, 120, 150, 160, 700, 800 and 900 models and the smaller 80 series. Rangefinders, automatic exposure and supplier-made lenses differentiated equipment for casual and advanced photographers.

The Canonflex of 1959 introduced the R-mount SLR line. The FL mount followed in 1964 with stopped-down TTL metering and retained the breech-lock concept. Canon developed large synthetic fluorite crystals and released the FL-F300mm f/5.6 in May 1969. The company also diversified into calculators and copying technology and changed its legal name to Canon Inc. on 1 March 1969 to reflect a business no longer limited to cameras.

The Automatic 100 introduced pack loading and electronic exposure, then 100, 200, 300 and 400 series cameras varied body material, finder, timer, flash and lens. Manual 180, 190 and 195 models used Japanese shutters and named optics, giving the platform a professional branch.

The low-cost Swinger and its successors carried instant photography into youth culture and casual social use. Colorpack and other rigid-body pack-film cameras broadened the same idea, while portrait, identification, medical and industrial systems made immediate prints useful far beyond family snapshots.

Canon introduced the FD system and professional F-1 in 1971. FD retained the earlier breech-lock physical concept but added full-aperture metering and information exchange intended for automatic exposure. Fourteen FD lenses appeared together at launch, and the wider F-1 system was supported by more than 180 accessories. Canon simultaneously expanded plain-paper copying, laser printing research, overseas production, and semiconductor lithography.

The folding SX-70 combined reflex viewing, a collapsible mirror path, motorized ejection and integral film that developed in daylight. Alpha revisions improved the mechanism, Sonar added ultrasonic autofocus, and rigid-body OneStep and Pronto cameras translated the format into mass-market products.

The AE-1 of 1976 integrated a CPU into a mass-market 35mm SLR and was followed by the multi-mode A-1. New FD lenses appeared in 1979 with a faster fit-and-lock action while retaining interchangeability with earlier FD bodies. The T80 of 1985 provided a limited autofocus transition through dedicated AC lenses, but Canon concluded that a more extensive electronic system would require a new mount. Canon also began supplying laser-printer engines to Hewlett-Packard during this period.

Higher-speed 600 film supported flash-equipped box cameras and folding SLR 680/690 models. Spectra, called Image in several markets, used a wider integral format, while Captiva, i-Zone and JoyCam pursued different print shapes and uses. Similar styling did not make these film packs interchangeable.

Polaroid prevailed in its instant-photography patent case against Kodak, leading Kodak to leave the field in 1986. Yet dependence on chemical instant imaging became a liability as digital photography grew. The original Polaroid Corporation entered Chapter 11 in 2001 after a difficult diversification.

Canon launched the EOS 650 and EF lenses in March 1987. EF replaced mechanical lens-body couplings with electronic communication, located the autofocus motor in each lens, and was not natively compatible with FD. The EOS-1 of 1989 extended the system into professional use. EF manufacturing expanded through Japan, Taiwan, and Malaysia, while Canon developed digital cameras and early professional digital SLR products around the EOS architecture.

The EOS D30, marketed in October 2000, paired the EF system with a Canon-developed 3.25-megapixel CMOS sensor and Canon signal processing. The EOS-1D and full-frame EOS-1Ds brought the digital system to professional work, while the lower-priced EOS 300D widened access. EF-S added APS-C-specific lenses within the EOS SLR family. Canon continued selling the EOS-1V film body until 2018, although an official sales-end notice does not establish its final production month.

Assets and the Polaroid name passed through a reorganized company and later Petters Group ownership. Instant camera production and the remaining film lines stopped in 2008, and the post-reorganization company entered bankruptcy that December amid the wider collapse of the Petters organization.
The Impossible Project organized around Polaroid's surviving Enschede plant and rebuilt integral-film production with altered materials and supply chains. Film sales resumed in 2010, preserving the physical Polaroid format even though the original Cambridge corporation and its formulas did not continue intact.

The EOS M of 2012 introduced the separate EF-M mirrorless mount for APS-C cameras and dedicated EF-M lenses. Canon also developed Cinema EOS and continued to expand digital SLR and professional video systems. The corporate group broadened further into network cameras and medical systems. No clear Canon announcement found in this search assigns one formal end date to the entire EOS M system.

In 2017 the majority shareholders behind the Impossible Project acquired PLR IP Holdings, owner of the Polaroid brand. Polaroid Originals followed, and the businesses were integrated under Polaroid B.V.; the current company again develops instant cameras and manufactures film at Enschede.

Canon launched the full-frame EOS R system in 2018. The RF mount retains a 54mm internal diameter but shortens the flange distance to 20mm and uses a 12-contact electronic interface. Canon adapters support EF and EF-S lenses on RF bodies, but RF and EF-M remain separate native systems. Canon Inc. continues to operate across printing, imaging, medical, and industrial businesses, with lens and lithography production centered in a global manufacturing network.
