RadioShack—the long-troubled hobbyist-turned-battery store you probably didn't know was still in business—officially went the way of the Blockbuster on Thursday, filing for Chapter 11 bankruptcy protection. It was 94.

According to The Wall Street Journal, the 'Shack plans to sell between 1,500 and 2,400 of its 4,000 U.S. retail stores to Standard General and shutter the rest.

It's not all bad news, however: Using a "store within a store" model, RadioShack will continue to operate as a hollow shell of it's former self in up to 1,750 of the locations, which will primarily be branded as Sprint stores.

At this time of sorrow and loss, let's celebrate the company's better days with this vintage ad for a (let's be honest) pretty dumb gadget that never should have caught on.
