Microsoft is running a national ambient campaign to promote its “I’m a PC” theme, using digital advans which will visit major UK cities and invite consumers to upload their own “I’m a PC” content to the Microsoft website.

The campaign has been put together for Microsoft by specialist media agency Ambient Media UK. Ambient is organising Microsoft-liveried digital advans, provided by SA Screen Media, which will travel round the country for 18 days during December.

Ads will be displayed on 120 x 90 inch high quality screens on the side of the vans.

Media agency for the campaign is Universal McCann and poster specialist is IPM.

Ambient Media UK has also been appointed by SA Screen Media to be its London sales house. Besides the Microsoft campaign, Ambient has used SA advans on campaigns for Disney, Nokia and Camelot.
