wjcofkc writes: The decline of Radio Shack has been painful to watch, and now CNN Money reports that they will be closing 1,100 of their stores, totaling 20% of their brick and mortar presence. Radio Shack has also publicly admitted its current stores are out of date and in need of a massive overhaul. But the number one culprit has been a continuous slide in sales down a steep slope in the area mobile device sales. A few years ago, in a bid to expand it's customer base, Radio Shack made a bid to return to it's roots as a hobbyist electronic components retailer. Apparently the extra traffic hasn't been enough to make up for their failings. The article mentions that some of their stiffest competition is coming from online retailers. The big question is, in order to ensure their survival, would Radio Shack be better off continuing to phase out their brick and mortar presence while making substantial efforts to expand as an exclusively online retailer?
