12 and 9 researched events on one shared scale. Polaroid 1932–present, Zeiss Ikon 1926–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
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.
Dated in the sources as “1940s”. Decade wording normalized to its full calendar span for scaling.
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 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.

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.

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.

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.
About us · Polaroid and Polaroid Originals to further integrate business units
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.

ICA, Contessa-Nettel, Ernemann and Goerz merged under Carl Zeiss Foundation influence to form Zeiss Ikon AG with headquarters in Dresden.
Early catalogs retained many predecessor-derived plate and roll-film families while the company developed clearer standardized lines including Box Tengor, Nettar and Ikonta.
The Contax 35mm rangefinder system, Super Ikonta folders, Ikoflex TLRs, Tenax, Contaflex TLR and Movikon cine cameras broadened the portfolio.

Dresden works were dismantled, sequestered and nationalized, leading through VEB Zeiss Ikon toward VEB Kamera- und Kinowerke and Pentacon; the western legal seat and camera operation were rebuilt in Stuttgart.

Historic camera production ceased in 1972. The security branch continued and is now within ASSA ABLOY under IKON; Carl Zeiss later used Contax through Yashica/Kyocera and revived the ZEISS Ikon camera with a Japanese partner from 2004 to 2012.
