Last fall I was living in Seoul's Gangnam district when the British retailer TESCO introduced its "virtual shopping" experiment at a nearby subway station. It appears that this experiment has achieved some degree of success in Korea and may spread to other markets around the world. Forbes, in an article entitled "The future of shopping is virtual," reports that, the retailer Peapod is trying out a similar scheme in Chicago. As noted in that article, virtual shopping pioneered in South Korea. The video below provides an interesting glimpse into the fast moving Korean marketplace and how retailers are exploring new uses for those smart phones that nearly all consumers will soon carry.
