The idea of applying for a .bzh top level domain was first mentioned in 2004 by Christian Ménard, member of the French Parliament. The introduction of the top level .cat domain in 2006 revived the idea. An online petition, initiated by Mikael Bodlore-Penlaez via the Geobreizh.com website, has mobilized public opinion and encouraged local authorities to state public support for this project. The Conseil Général d'Ille et Vilaine (14 April 2006), the Conseil Régional de Bretagne (14 June 2006), the Conseil Général du Finistère (15 June 2006) have unanimously supported the idea of creation of a. bzh.
In 2007, the Regional Council of Brittany initiated a feasibility study of the project. Under the direction of a steering committee involving various stakeholders, this study has resulted in 2008 in the establishment of a formal structure to support the Breton application : www.bzh.
The www.bzh association is responsible for establishing the application, gathering the necessary funds to ensure its submission and its promotion within the Breton community. The association in December 2008 has been granted financial support from the Conseil Régional de Bretagne. The online petition has so far received more than 21,000 signatures.
