Another breakthrough in making film practical for home users was the introduction of safety film in the 1920s. Earlier “nitrate film” required special handling and storage, even after it was exposed and developed, since it is extremely flammable and has even been known to spontaneously catch fire as it gets older.
Many competing film formats were introduced in the early decades until 16 mm safety film was introduced by Eastman Kodak in 1923 and became a standard in the non-professional market. Although 16 mm had the advantage of users not being tied to one equipment manufacturer and there were obvious cost advantages compared to standard 35 mm, it was never able to eliminate smaller formats and it eventually was relegated to professional users, particularly in the education market.
