OIKOS commissioned a Facebook contest to increase engagement with its interactive campaign. The contest involved users selecting an ending to a choose-your-own-adventure-style ad, which aired on both television and YouTube (see it here). Every two days, OIKOS released a new “video battle” on its Facebook page and asked users which ending they prefer (should Simon end up with the mustached lady? The old Greek grandmother? etc.). Participants were entered in a draw for a trip to Greece. Elements included: contest landing page, prize list, 13 video battle CTAs, pre-filled Facebook messages, pre-filled twitter messages and a newsletter to further buttress engagement.
