Video Release Information in Video Business
Video Business is a trade publication for producers and distributors of video product, primarily in the US. It's a publication from the same people who publish Variety, the entertainment industry trade paper. I used to work for a distributor, and I still get this electronically - it's always interesting to read to see what the trends are. And sometimes there's cool stuff too! Here's an announcement about "The Next Doctor."
I'll let you know if I find anything else of interest.
