Vodafone 'all your mates in one place' by Dare

Vodafone has created 1,400 branded circles on streets across the UK as part of a new campaign to promote its new Vodafone 360 service.

Devised by Dare, the ambient campaign encourages consumers to invite as many friends as they can to stand in and around one of the circles, with the team with the most people in one place winning a £36,000 experience of a lifetime prize.

There will also be daily prizes of £360 for the most people in a circle and the most creative entry that day.

A microsite has been set up to raise awareness of the contest, which will also be promoted through social network sites and a viral, starring Lewis Hamilton and members of the England cricket team.
