It's obvious in hindsight that the hobbyist market moved, and Radio Shack moved in a different direction. The hobbyists went to Raspberry Pi, Arduino, and quadcopters. Sales of electronics components, wired phones, and Radio Shack PCs dried up almost overnight. Radio Shack went with their remaining big sellers: Cell phones, sound systems, and other consumer electronics that dropped in price and appeared in Walmart, Best Buy, Staples, etc. In the past few years, there was not much to be found in Radio Shack that you couldn't find at Walmart.
