Misunderstanding quality
Kodak, of course, ruled their world. They were as close to a monopoly as they could get for generations.
Along the way, though, the company made the mistake of misdefining quality. They thought that what would ensure their future was better fidelity film. And without a doubt, they delivered on the promise of ever better film stock, with all the things a professional photographer could hope for.
Polaroid, for a while a disruptive competitor of Kodak's, fell into precisely the same trap. As they gained market share, they doubled down on image quality, raising their prices to support cameras and film that would compete with Kodak's leadership in fidelity.
It turns out that what people actually wanted was the ability to take and share billions of photos at vanishingly small cost. The 'quality' that most of the customer base wanted was cheap and easy, not museum quality.
This confusion happens all the time. Quality is not an absolute measure. It doesn't mean 'deluxeness' or 'perfection'. It means keeping the promise the customer wants you to make.
