Crossroads is a British television soap opera that ran on ITV over two periods – the original 1964 to 1988 run, followed by a short revival from 2001 to 2003. Set in a fictional motel in the Midlands, Crossroads became a byword for low production values, particularly in the 1970s and early 1980s. Despite this, the series regularly attracted huge audiences during this time, with viewership numbers reaching as high as 15 million viewers.
