I distinctly remember that when PBS did a documentary on the 1984 Presidential campaign, the reporters turned away from the Mondale-Hart battle to ogle a Model 100, and the show turned into a user group.

So what happened? There are lots of theories on that.

First RadioShack couldn't scale with the PC revolution. When IBM (IBM) launched its PC, RadioShack was stuck with incompatible CP/M machines.

It became an importer (the Model 100 was actually made by Kyocera in Japan), then slowly evolved into a parts store. By the early years of this century I would sometimes find myself dragging the kids into a musty RadioShack in a mall, searching for a cable or an obscure battery. I think they were scared of the place. It was next to a movie theater. They didn't know what a movie theater was, either.

As late as December 1999, RadioShack was worth almost $77 per share. The next year it traded for some time in the 60s. Then it slowly bounced downward, each peak lower than the last, each trough more worrying. But it still paid a dividend until 2012. On Wednesday morning, it's trading at about $2.30.

For some reason, RadioShack threw up a Super Bowl ad this year, filled with celebrities from the 1980s such as Hulk Hogan and Alf. The ad got good reviews, and lots of mentions on social media, but the horrible quarterly numbers were already in.

Some analysts think RadioShack's demise represents the end of retail as we know it. Amazon.Com (AMZN) is taking over the world, they say.

Other analysts ask why RadioShack hasn't reinvented itself as a "maker space," devoted to 3-D printing, which they see as analogous to the PC revolution of RadioShack's heyday.

Certainly RadioShack's attempt to make itself a haven for mobile device lovers seems doomed. Phone companies have their own stores, cool kids go into Apple Stores, and there's nothing special about the company's mobile offerings that anyone would cross the street for.

The fact is that, like the celebrities it brought into its Super Bowl ad, RadioShack got lucky once. It fit the zeitgeist of a time, then woke up one morning to find its time was past.

So give your dad a hug today. When Yahoo (YHOO) gets bought out by Disney (DIS) or Facebook (FB) crashes and burns, you'll understand how he feels.
