The task was to use the internet to communicate the relaunch of the mobile phone provider VIAG Interkom to o2. In the web, a core target of 'Early Adopters' (buy newest gear) and 'Opinion Leaders' (explain phones to friends) should learn what the multi-channel campaign of the o2 bubbles stands for.The agency applied a Webbuster as a world premiere: taking over a leading portal for one day with 100% of the ad-space (100% 'Share of Voice') and colouring the computer, internet, and mobile-channels in o2 bubbles. The results were measured both with detailed tracking and a brand impact market research.
