What is 8mm Film?
An inconvenience, however, was also hidden in film formats main benefit. That is, 8mm filmed on two separate edges to maximize time for filming. This required turning the film spool over midway so it could film on the opposite edge. Once developed, however, it was turned into one strip of film that could give you roughly four minutes of footage.
While color 8mm footage was eventually available, you've likely seen many black and white 8mm films taken throughout the 1930s and 1940s. The history on 8mm film, though, has some very interesting details that go right up to the 1990s when it was officially retired as a home filming format.
Effects on the Great Depression and the Professional Market
After being the filming standard, 8mm gave way to Super8 in 1965, which would be the format you'd remember if growing up in the Generation X era. Attempts were always made to simplify the standard 8mm format, but it generally stayed the same. Some people continued to use it as a stylistic filming tool up until the early 1990s when Kodak stopped making it.
You guessed right if you thought it wasn't gone completely. However, only one company in the U.S. still sells original 8mm film stock. A 100-foot spool of color 8mm film will cost you around $42 at the above site.
