I am very confused over the histories and names of Captain Marvel, Shazam and Shazzam.
The only ones I am familiar with are the recent incarnation of the Billy Batson version. The young kid that becomes Captain Marvel upon uttering his magic word. I have looked over a few of the Jerry Ordway issues, but I wasn't that keen - already spending too much on comics at that period already.
I am also vaguely familiar with the Marvel Comics Captain Marvel, the female, black Capt. M that had some kind of light-based powers c. 1982.
Other than that I am lost.
