As a non-American, I'm completely unfamiliar with RadioShack, except for having seen the name often, and often associated with some sort of strong feelings. Why do they hold such "high" status, or stay relevant in discussions? I could not really gather an answer to this from their Wikipedia page; perhaps I'm just imagining the whole attitude?
(Adafruit's collection I've browsed online, and possibly even ordered something from there; RadioShack appears not to even ship outside the US.)
