American Comics Group

American Comics Group (ACG) was a small publisher during the Golden and Silver Age of comic books that existed from 1943 to 1967 publishing mainly low key "horror" and also ran superheros. 
 
In 1996 Roger Broughton, owner of Sword In Stone Productions, purchased the rights to the remaining Charlton Comics and characters (the Fightin’ 5, Gunmaster & Bullet Boy, Atomic Rabbit, and after being bought from Fawcett, Don Winslow) that had not been bought by DC comics, who now own the rights to most of Charlton’s superheroes.  

Later he also bought the rights to the titles and characters of the old ACG comics group ( Magicman, John Force: Magic Agent, Nemesis, Herbie “the Fat Fury” Popnecker, the Hooded Horseman, Cowboy Sahib, and Commander Battle and his Atomic Sub.)  

In 2002 he changed the name of his company to the "Charlton Media Group".
Since then he has announced attempts to revive the various titles and characters that he owns, but so far nothing new has come of it other than a number of reprints of Charlton and ACG material in Europe, and the licensing of the rights to produce new Nemesis, Magicman and Herbie stories to Dark Horse.
As yet the other characters remain untouched.  

However if you have a snappy idea on how to revive Cowboy Sahib, Atomic Rabbit or Bill Battle and his Atomic Commandoes… well good luck.
