SHAZAM  is an acronym 
SHAZAM is an acronym for various historical or mythilogical persons such as Solomon and Atlas, etc and their qualiies , ie:Solomon's wizdom, Atlas's strength, etc.  Hercules? I forgot them all.  Billy Batson was a crippled newsboy - perhaps later on he became a reporter, but I only read the original strips in the 40's.Billy used one crutch as he walked with his newspapers under his other hand.  Perhaps Shazam, the wizard was the old guy who brought or met Billy in the cave containing the statues of the aforementioned characters and empowered him with super qualities. ```
