The bottom really fell out of the (colour) film market in the 90s when the newspapers switched over to digital cameras like the Nikon D1, 2.7MP was for all intents and purposes "good enough" to replace film in that industry and the speed advantages were overwhelming. Since then (B&W) film has been about artists and hobbyists, so the industry has been limping along longer than you think.
It is more of an issue of scale - kodak was set up for huge volumes on huge lines, while Ilford was set up for smaller runs and is doing ok. Black and white film is over 100 years old, and is fairly well understood tech, you can make your own if you really want (glass plates are relatively easy), although colour is much harder.
Why worry now? We'll deal with that when we get there.
