Sky2 is to launch an eight-part online-only documentary called 'Abduct Me', in which presenter Chris Bell tries to get abducted by aliens. According to New Media Age, the show will be intertwined with an online community, encouraging viewers to upload their own videos, photos and experiences on alien-sightings and abductions - clearly appealing to a particular niche of the market.

It sounds like a very serious attempt to create a genuinely interactive experience, and they hope to create an on-going series and/or brand. It also seems a good way to create compelling content with relatively modest investments, which, after all, is supposed to be one of the great things about online.
