Texting Keith Olbermann

Two years after the texts first started and despite never having met, BBC News anchor Ros was now exchanging more texts with legendary US broadcaster Keith Olbermann than anyone else apart from his wife. They often arrive as he's making the late night trip home after his show - and they continue when he's catching up with his wife in bed. It's time to ask Keith 'why?' and to ask his wife what she makes of it.
