To be clear, Radioshack and Circuit City were two distinct companies in the US. From a cursory look at Wikipedia, Circuit City was liquidated in 2009 (and later revived), and Radioshack is still operating stores.
Yeah—that Wikipedia link goes into the more complex history.
I just remember the RadioShack near my hometown that was full of walls of components. Now you're lucky to find a blank F-connector at The Source in the largest city in the country. Sentimentality got to me.
That said—for other Torontonians, or visitors, there's an awesome (edit: AWESOME) shop on College St between Spadina and Bathurst called Creatron: https://www.creatroninc.com/ (and surprisingly don't discount Long and McQuade [repair shop, Bloor St] for good quality pots and switches, albeit at a markup).
Radioshack is still around, but has scaled back extremely.
From thousands of operating stores to 500. Had a few in our area all close, so instead of 2-3 miles, now requires 20 miles to get to one. Effectively to some towns/cities it feels like Radioshack is no more because of such a drastic hit to their footprint.
