Introduced in 1972 by Eastman Kodak, the 110 cartridge film format was a huge success for amateur photographers in the United States, England and beyond. Following the equally popular 126 cartridge format (launched in 1963), the 110 film was only 16mm in width allowing cameras to be much smaller, launching Kodak's "Pocket Instamatic" campaign.
With a 110 camera in every household, cameras and film were easily obtained for three decades until Kodak (and other companies) discontinued the film in 2009. Popular for its unique grain and "look," photographers continue to use the last batches of 110 film in vintage and new Holga cameras. It's been reported that European company Adox will introduce new 110 films in 2011.
