The group was organized by Sylvester Pemberton, the original Star-Spangled Kid, in Infinity Inc. #1, when a number of JSA protégés were denied admission to the JSA. They instead formed their own group. Members of Infinity, Inc. were known as Infinitors.
The series ended in 1988 with the death of the Star-Spangled Kid (by then known as Skyman), and presumably the group disbanded shortly thereafter. Several members have gone on to supporting roles in other comics series. Fury filled a pivotal role in The Sandman and is the mother of Daniel Hall. Hourman, Obsidian, Nuklon (as Atom Smasher), Silver Scarab(as Doctor Fate), and Power Girl eventually joined the 21st century incarnation of the JSA.
Originally, the series took place on the parallel world of Earth-Two, but in 1986 it was merged with the rest of DC continuity following Crisis on Infinite Earths. From then on, they shared their spot as Los Angeles’ superteam with the Outsiders, and were involved in a crossover with the New Teen Titans.
