What characteristic defined the original Kodak mechanism?

Answer

Closed-loop system

The genius of the Kodak invention was not solely the mechanical camera design but the accompanying business strategy, which established a closed-loop system. This system meant that the company controlled the entire user experience from beginning to end: selling the hardware, providing the necessary consumable (film), and mandating the after-sale service (development and reloading). This integrated structure ensured predictable revenue and guaranteed results for the customer, a principle that echoes in modern sales of devices requiring proprietary consumables or mandatory ongoing service.
