Sears is an amusing example given their mail-order history. Ultimately they shut down as a direct result of making no attempt to innovate or even mimic the innovators since those glory days.
Walmart, Target, Home Depot, etc. embraced the 21st century and are doing just fine. Others like Chewy only came about as a result of the new trends.
BB&B bought its way into bankruptcy by taking on debt to fund a multi-billion dollar stock buyback; external competition (including Amazon but primarily Walmart) was a secondary factor.
Are those failures a direct result of Amazon existing? I would venture to bet it’s one of the reasons but I would also point out that Walmart has done a lot of damage as have poor management decisions in a number of the companies you listed. Correlation is not causation.
> Other retailers continue to shutdown and it's a direct result of Amazon.
It is not Amazon, it is online shopping in general. They never were going to survive a world where their competition can sell the same goods without having all the capital and labor expenses of a storefront.
A few of the big ones will survive due to convenience, but the niche stores where you do not need the product today or tomorrow have no competitive advantage against a website, outside of a few high end stores where richer people can afford to pay extra for the shopping experience.
Sears, JCPenney, and Bed Bath & Beyond are, to the best of my understanding, victims of vulture capitalism. Sure, Amazon didn't help, but they would've been in decent shape if Wall Street hadn't swooped in, drained them dry, and discarded the desiccated husks.
Sears, JCPenney, Bed Bath and Beyond are just a few dominoes to have already fallen.
