What it had to solve
Tesco's Korean arm Homeplus was Korea's number two supermarket behind E-Mart, which had more stores. With commuters short on time, the brand chose to fight store count with convenience and grow its online channel.
How it works
In late 2010 Tesco's Korean arm, Homeplus — the country's number two supermarket behind E-Mart — turned subway platforms into stores. Cheil Worldwide Seoul covered walls with realistic, life-size displays of grocery aisles; commuters scanned QR codes with the Homeplus app, paid on the spot, and the items were delivered to their door from a nearby store.
The logic was simple, as the campaign's own film put it: let the store come to the people. Homeplus had fewer stores than E-Mart, so it fought store count with cybersmarts, and Seoul's commuters had little time to shop. The first three-month campaign drew 10,280 visits to the online store, raised new registered members 76% and lifted online sales 130%, according to The Independent.
The format kept growing: in August 2011 Homeplus opened a permanent 'Smart Virtual Store' at Seolleung station displaying 500 products across seven pillars and six platform screen doors, with 650,000 app downloads by July, according to The Hankyoreh. The campaign beat 2,895 entries to win the Media Grand Prix at Cannes Lions 2011 — South Korea's first in that category.
Why it lands
- It converted waiting time into shopping time — the audience was captive, and the offer was convenience rather than a discount.
- It fought a bigger rival's store count with a channel that needs no real estate, turning the ad medium itself into the store.
- QR scanning became part of an everyday habit at scale, making the phone the checkout.
- The results were measurable in business terms — sales, members, app downloads — so the Cannes jury could award more than craft.
What it did
Online sales rose 130% and new registered members 76%, with 10,280 online-store visits during the first three-month campaign (The Independent); by July 2011 the app had 650,000 downloads (Hankyoreh). The work beat 2,895 entries to win the Cannes Lions 2011 Media Grand Prix.
What you can take
Instead of buying more reach, the brand bought more convenience: it turned the place where the audience already waited into the store, so the ad medium itself did the selling.
Since then
The virtual store won South Korea its first Cannes Media Grand Prix and became a global reference for QR and online-to-offline retail; retailers abroad adopted similar scannable wall stores, and Homeplus extended the format on Seoul's streets into 2012. The case remains a standard early example of turning media space into a transactional channel.
