Retail is changing faster than ever. New technology is increasingly being infused into stores, and the results are finally starting to show. Though there has been a lot of talk about how online shopping is changing the retail landscape, forcing traditional shopping centers like malls to close, it's only now that the future of the industry is truly coming into focus. And yes, it's digital, just as we were promised. Amazon and, more recently, Nike, have debuted store concepts that put their digital smarts front-and-center as they offer new experiences to customers. The advent of tech-focused physical stores proves that brick-and-mortar retail isn't going anywhere soon.
