Which significant technical achievement paved the way for the consumer Kodak camera system?
Answer
Transitioning from selling dry plates to developing flexible roll film.
Before the iconic box camera could be realized, a major technical barrier related to the photographic medium had to be overcome. George Eastman had previously been involved in supplying dry plates. The critical step that enabled the simple, consumer-friendly camera—which used a pre-loaded roll sufficient for 100 exposures—was the successful development of flexible roll film. This innovation represented a complete technical departure from the rigid and cumbersome older formats, forming the essential foundation upon which the entire revolutionary Kodak system, including its simple name, was built.
