Tesco is the leader in the field of retail social media marketing, as noted in the past, but have really outdone themselves with this experiment  with a virtual store in railway stations in South Korea.

The speed at which innovations are being tested, and if implemented is increasing, but usually we would expect a smaller business to be sufficiently agile to try some of this stuff, but Tesco is building a really impressive track record.

Australian supermarket retailers are in the dark ages by comparison, although some of the smaller food service retailers are starting to move with location and coupon promotions, but I would expect Coles particularly, now managed by a veritable cricket team of ex-Tesco Poms to  make the running amongst the big boys.
