Despite the difficulties and challenges its production often presented, drama had become a central part of the BBC's television schedules; a BBC audience research survey conducted in 1937 found that 90% of those replying generally enjoyed the drama productions, a figure equalled only by outside broadcasts. In Christmas week 1938, drama accounted for fourteen of the twenty-two hours of programming broadcast. By the following year, drama programming had fifteen producers working on it, compared to nine for all other types of programmes combined.
