The NZN Buchverlag was founded as early as 1946 to publish articles and essays for the Catholic daily Neue Zürcher Nachrichten.

It continued independently until 2005. Since then, it took the name of Catholic "Edition NZN bei TVZ" and went on publishing under the wing of the Protestant Theological Publishing House in Zurich.

With the integration of "Edition NZN", publishing house TVZ has set a strong ecumenical signal.
