I've posted a few items about the history of Christian film in the past, but this is the first I've seen that's scholarly, with footnotes and bibliography. Although the focus is much more on the early days of Christian film than more recent times, it's detailed, interesting and insightful. Worth a read to understand our rich heritage.
"Literally thousands of Christian films have been made over the last 65 years by dozens of companies. The vast majority of those made 1939-1980 have never been released on home video formats and remain buried in the elephant's graveyard of 16mm. This is a shame because they are important to social history and film history, shedding light on both the church's attempts to utilize a new medium for the spreading of God's Word, and the forgotten backwater of independent religious film producers. It's also a shame because once the films are gone, they're gone."
