APS

The APS system was introduced in 1996 with participation by Kodak, Fuji, Agfa, and Konica. Other companies got in on the act, such as Boots, the English chemist chain. Many people bought new cameras and many film developers invested in new processing equipment. The directors and shareholders of the companies behind the 'innovation' rubbed their hands with glee.
It was an inferior system and lasted until 2011 although anyone with half an eye on the camera market would not have bought into APS for a good many years prior to 2011. APS cost more and gave inferior results to 35mm. Like all the cartridge-based systems before it, it ultimately failed. Caveat emptor.
