Both Atlus and NIS published Disgaea in America/Europe.  This is why many have come to think Atlus made the game.  Or have you not heard in almost every thread like this 'I sure hope Atlus makes a new Disgaea' or something to a similar effect.

Never actually heard that mistake before, but you are right that the first Disgaea was published by Atlus in NA for some amount of time.  According to the Wiki it was also published by Square Enix for Europe and Ubisoft for Australia.
