If the question is how do you revive a company with a dead reputation and little sales like Kodak, but tailored to that case specifically:

Kodak, and every other retail company, creates products that rely on not only their product, but also their brand. Companies with semi useless products sell them all the time

K-cups, somehow took an infinitely reusable thing like a coffee maker and turned it into a tiny plastic trash cup Dasani water is awful tasting, terrible for the environment, and expensive, but they go where they’re needed

And a million other examples, selling a product isn’t about being the best or even having something good. It’s really a matter of branding and marketing strategy.

Rebrand kodak to a bespoke camera with a bunch of little camera accessories, a small preview screen but a bunch of little knobs, lean into the fact that it’s not a smart phone. Print on the device like those urban outfitter cameras, make a snapchat style camera that will only keep photos for a day, do something different and target a specific audience and they could be revived as something different. Work on making a camera that can’t be reproduced by ai, human authenticity fingerprints for images or something.

Kodak as it was will very likely never make a comeback. They didn’t keep up.
