So ... is there anyway to reverse its course?
Well, If I'm Radio Shack's CEO, here are the facts I need to face:
1) Radio Shack cannot compete based on price or breadth of selection against big-box stores, let alone the Internet.
2) The initiative a few years ago to hire highly knowledgable staffers who could offer expert advice didn't work. It's just not economically feasible to employ people with those qualifications in a retail store, and anyway, that alone isn't going to keep the store afloat.
But I think there's still a way for Radio Shack to be a viable company; it would just require some radical changes.
Look at Build-a-Bear, across the mall corridor. The experience of building your own bear from scratch can't be replicated online. Sure, you can order a custom bear online, but kids love Build-a-Bear because they get to witness the stuffed toy's construction from start to finish. Build-a-Bear is as much an event as it is a store.
I think Radio Shack could fashion itself into something similar, but for electronics and gadgetry.
Remember those popular Radio Shack 50-in-1 science project kits? Imagine a Radio Shack where you come in, choose a project, and then build it right there in the store. A kid might come in and buy a robot kit, or a solar-powered race car kit, and they'd be able to assemble it there, with all of the tools (soldering irons, etc.) provided, and with assistance from trained (but not necessarily expert) staffers. STEM is really big in schools right now. Maybe Radio Shack could market itself as a place to pick up STEM skills, and even partner with schools.
But it wouldn't have to be limited to kids stuff. An adult might come in and participate in a DIY electronics workshop: "How to replace an electrical outlet" or "How to work on a circuit board."
Along the same lines, imagine if every Radio Shack had a 3D printer available to rent. You can upload a 3D model to its website, or choose a model in store, come in and watch the printing process, and eventually (yes, I know, it takes hours!) take it home.
With this sort of strategy, Radio Shack wouldn't necessarily need to recruit domain experts, because what would be needed is not a wealth of general knowledge, but some very specific knowledge about a relatively small number of specific projects. A highly motivated high-school or college student could be taught how to lead people in constructing the projects or running the workshops.
That is a Radio Shack I would totally patronize, and it's a strategy that shields the store from needing to compete solely on price or on breadth of selection.
