So was Fujifilm and they still exist and have a successful line of digital cameras

The point is, Ma Bell, the original AT&T, was a long distance company. That was their cash cow. That was their mind set. So the basically gave cellular away. Same thing as Kodak, they saw themselves as a chemical company not a photography company.

Truth is, ma bell should have thought of themselves as a telecommunications compay.

Exact same mistake.

And Xerox was a photocopy company and not a computer company right? /s

Nokia was a paper mill company. Not sure what you're trying to say.
