I've been enjoying "WW2 in Real Time", a YouTube-based week-by-week documentary wrap up events in the war 79 years ago. (Go, and subscribe if that's your kind of thing.) That means we're in 1940, during the Battle of Britain.
I've thought about reading the Radio Times in tandem since they're available, to get a better sense of the nature of the religious broadcasting. So, "today" Sunday, September 1, 1940 I see on the Forces radio schedule a variety of short religious programs, lasting from about five to thirty minutes, and ranging from talks, to hymn sings, to services. Smart: serving people who might not be able to break for a local, organized service or to listen to a fifty minute "full" service on the Home service. Serving people as they are is good ministry. I look forward to other insights.
Also, I note on that day an early show for the Forces featuring that epitome of World War Two home-fires entertainment, Vera Lynn. She is still living, aged 102. This is the past, but not ancient history.
