Here at Ralph we're massive fans of Charlie Brooker so we were cock and indeed a-hoop when we were chosen to create a viral for his Big Brother zombie-fest, mini-series Dead Set. Hundreds of thousands of terrified users later and it has became an online horror phenomenon driving huge levels of tune-in to the show itself. Interesting fact: 50 litres of blood was needed to create the gory scene, most of it fake.
