IKEA recently presented the results of a 2009-campaign which was launched to feature the opening of the new IKEA in Malmö:
a facebook profile (Gordon Gustavvson) was created and 12 pictures of IKEA showrooms were uploaded within a time period of 2 weeks.
This is how it worked: As soon as a picture were uploaded, fans could tag furniture and the one who tagged first, got exactly this furniture as prize – see IKEA-Facebook showroom
From Marketing point of view this is THE perfect campaign:
The promotion is easy to understand, supports the own products as well as the image of the company. It combines the advantages of the online- and offline-world and creates quite some buzz which pays back with high awareness and recommendation rates.
