Inside the Social Network: Facebook's Difficult Year, 9.00pm, BBC Two
Apparently this is a fascinating glimpse into Facebook and its various headquarters dotted around the world - including Dublin, of course.
These are places where food and drink are free, employees can skateboard and scoot around the corridors, and where the walls are dotted with inspirational posters, and there are Facebook Walls where staff can scribble down whatever's on their minds.
