Readers of a certain age will remember CompUSA, a defunct big-box computer retailer. What happened to CompUSA? It went out of business, then came back as an undead brand, then went away again.
In some ways, CompUSA was the epitome of 1990s computer retail. It had huge big box stores with aisles of software and upgrades. It sold desktop computers, including its own house brand, Compudyne, manufactured for CompUSA by Acer. But the business model didn’t work as well in the 21st century.
