Earth-37

Earth-37, a world of lawless heroes and cynical champions.  On Earth-37, technology accelerated during the '60s, '70s, and '80s.  The beat cellars of the '50s gave way to the underground Mars base colonies of the '80s and Europa bases of the '90s and then to the interstellar world of Tommy Tomorrow, Manhunter 2015, and Space Rangers. -Grant Morrison, The Multiversity Guidebook.
