Four 60-second mini episods have been created for broadcast on UKTV Play and via its social channels on platforms including Twitter, Facebook and Instagram. A partnership with Trinity Mirror means an on-demand boxset will be promoted.
Geek Island has been produced by creative agency Taylor Herring in partnership with UKTV Creative and directed by Jonathan Brooks for St Marks Studios.
It stars real-life eggheads, including University Challenge contestant Bobby Seagull and Miss England Stephanie Hill (who is undertaking a maths PHD), all of whom are on a quest to find intellectual stimulation on a luxurious island villa.
In a 60-second promo, a voiceover intones: "UKTV Play takes you to a Balearic party paradise where love equals MC2."
Geek Island has been conceived to promote UKTV Play's documentary and factual programming running throughout September, which spans 1,000 shows such as Wildest Africa and Impossible Railways.
Zoe Clapp, UKTV's chief marketing officer, said: "This is a lighthearted and affectionate parody of much-loved reality TV but reimagining it in a world where brains mean more than brawn and chemistry is scientific rather than physical."
