What is to be said of noir literature and radio?

I have read some Woolrich (under his other pen names too), James Cain, and one of my favorites Night of the Hunter by Davis Grubb.
On radio, I have listened to Bold Venture with Bogart and Bacall on Siena College radio and various other broadcasts on The Big Broadcast, WAMU. It would be interesting to find out how many of these kind of programs are still aired on radio.
