The phrase "Hiding behind (or 'watching from behind') the sofa" entered British pop culture, signifying in humour the stereotypical early-series behaviour of children who wanted to avoid seeing frightening parts of a television programme while remaining in the room to watch the remainder of it. The phrase retains this association with Doctor Who, to the point that in 1991 the Museum of the Moving Image in London named their exhibition celebrating the programme "Behind the Sofa". The electronic theme music too was perceived as eerie, novel, and frightening, at the time. A 2012 article placed this childhood juxtaposition of fear and thrill "at the center of many people's relationship with the show", and a 2011 online vote at Digital Spy deemed the series the "scariest TV show of all time".
