When we think of the BBC before the Second World War, we tend to think "radio", and when we think of the corporation after 1945 we think "television". But this is very much an oversimplification. For the whole of the 1950s, radio was more influential than television. And before 1939, there was the amazing adventure of the first experiments and broadcasts in television. This documentary from 1984 looks at television in the 1930s. You can skip the first few minutes, but the rest is very interesting (the image quality gets better after 20 minutes or so).
