When I first moved to the Pittsburgh area, there was a downtown ham/electronics store called Tydings Electronics. The owner had sold out to another store, South Hills Electronics. SHE eventually folded ALL of their over the counter retail stores in favor of wholesale & bulk sales, more lucarative. SHE is still in existence, although under another name due to mergers, but they don't want to be bothered with the average person.
There had also been a rival downtown store called Cameradio. Yup. Cameras along with radios. They too were bought out by another store, and got folded into Cam/RPC, and their customer retail phased out.
So the corporate entity behind Electronics Center may still be around, but the retail store may have been deemed not profitable or not profitable enough.
