The JSA remained inactive for some time after the events of “Zero Hour“, but the surviving members (the Flash, Wildcat, and Alan Scott, (now going by the name Sentinel) have remained active throughout the DC Universe, having been placed as reserve JLI members, as evidenced in Justice League Europe #50.
The Justice Society was revived as a monthly series called JSA in 1999 which mixed the few remaining original members with younger counterparts. This incarnation of the team focused on the theme of generational legacy and of carrying on the heroic example established by their predecessors. The series was launched by James Robinson and David S. Goyer. Goyer later co-wrote the series with Geoff Johns, who continued to write the series solo after Goyer’s departure. The series featured the art of Stephen Sadowski, Leonard Kirk, and Don Kramer, among others. It featured a story by Pulitzer Prize winner Michael Chabon.
During the events of Infinite Crisis, some of the surviving Golden Age characters, such as Wildcat and the Flash, are transported to the new “Earth-Two”, as created by Alexander Luthor, and seem to recall the existence of the original one, albeit vaguely.
