We never had blockbusters here, but our local equivalent is actually still doing quite well. I think streaming movies is more popular, but a lot of people go there to rent music CDs. Actually buying physical music albums is really expensive.
We still have Toys R Us too actually, I think it does pretty well here for the most part.
So I guess my answer defaults to Radioshack.
There’s still a running RadioShack out in Dickson TN that I visited once. It’s actually a fantastic store to have nearby for electronic hobbyists who need weird adapters on a whim without waiting a few days to a few weeks for online shipments. I understand why it went mostly under, but as someone who was born in 2000, it was a little sad to realize that those stores mostly only exist for niche markets now.
