I've been pretty involved in Reel Magic Magazine since the beginning, and it's truly great. Each disc runs for approximately two hours, starring David Regal, Garrett Thomas, and other feature magicians. It's like a normal print magazine, but all done on video.
In the more recent issues, there's a video file on the disc so you can put the magazine on your iPhone or other device. There are also bonus PDFs in some issues.
I recommend it!
