Neuromancer did it first

To be fair, the Sprawl and Blade Runner did it more or less at the same time (I think it was Burning Chrome, Blade Runner, Neuromancer, but it doesn't really matter).

They sort of condensed something that was floating in the zeitgeist, the collective subconscious, of the late seventies / early eighties, and managed to completely independently create stories that could almost, aesthetically and by their philosophy, be set on the same world.

(And, let's be fair to Mike Pondsmith too, his game, while published a bit later, was quite genre-defining, too, even if it had been clearly influenced by the former.)
