Unity was appointed following a competitive pitch to a consumer-led brief.
The Oculus Rift kits, which retail for £549 in the UK, launched to consumers in the US earlier this year and in the UK last week.
Oculus Rift, which allows users to view films and video games in what is billed as an emersive VR environment, is being sold in the UK from retailers John Lewis, Curry’s PCWorld, GAME Digital, Harrods and online via Amazon. A series of demos of the technology are to be held at retailers over the coming months.
Unity, the UK's 75th largest agency, declined to comment. PRWeek contacted Facebook but received no reply at the time of publication.
The launch of Oculus Rift (above) comes as brands and agencies are taking an increasingly close look at the opportunities of VR.
