Is RadioShack completely gone?

So, I've been hearing rumors that RadioShack, the once-ubiquitous electronics retailer, is no longer in business. Is it true that RadioShack is completely gone, or is there still some hope for the company to make a comeback? I remember going there as a kid and being fascinated by all the gadgets and technology they had on display. It's sad to think that such a well-known brand could be on the brink of extinction. Do you think there's any chance RadioShack could turn things around and become relevant again in the marketplace?
