Some of these were regional but the pictures definitely bring back memories. Each store had a different feel, was targeted toward a slightly different audience, and all were fun to run around inside and look at the stock. You knew that Radio Shack would have a limited software selection but you could play with some super expensive headphones or TVs, you knew Toys R Us would have lots of rarer video games and stations to play demos at, at Circuit City you knew you'd get bugged by an associate every 3 minutes inside the store.
A lot of the electronics stores weren't really directly affected by online shopping competition, but by acquisitions and consolidations. Best Buy ate up Musicland (Sam Goody, Suncoast, Media Play), Barnes & Noble gobbled Babbages, etc. Those were in turn affected by Amazon in the 2000s.
Running around the racks at Media Play was an experience; when they began remodeling along with everyone else to a more "open floor" design it really did feel like the beginning of the end.
Am very happy we have a Microcenter nearby, it's been essential for so many things.
