For ~50 years, Radio Shack rode major trends in consumer electronics quite well. Amateur radios, walkie-talkies, CB radios, home stereos, home computers, cell phones, they did it all (except interestingly PCs they didn't do so great).
It was only when electronics became so mainstream, competition increased and profits became marginal they couldn't survive.
It's too bad, but if we're smart instead of over-analyzing this, we'll should keep our eyes peeled for the next industries that will go under.
