Hachette (French pronunciation: [a.ʃɛt]) is a French publisher. Founded in 1826 by Louis Hachette as Brédif, the company later became L. Hachette et Compagnie, Librairie Hachette, Hachette SA and Hachette Livre in France. After acquiring an Australian publisher, Hachette Australia was created; in the UK it became Hachette UK, and its expansion into the United States became Hachette Book Group USA.
It was founded in 1826 by Louis Hachette as Brédif, a bookshop and publishing company. It became L. Hachette et Compagnie on 1 January 1846, Librairie Hachette in 1919, and Hachette SA in 1977. It was acquired by the Lagardère Group in 1981. In 1992 the publishing assets of Hachette SA were grouped into a subsidiary called Hachette Livre (French pronunciation: [a.ʃɛt liːvʁ]), the flagship imprint of Lagardère Publishing. Hachette has its headquarters in the 15th arrondissement of Paris. In 1996 it merged with the Hatier group. In 2004, Hachette acquired dictionary publisher Éditions Larousse.
In 2002, UK publisher John Murray was acquired by Hodder Headline, which was itself acquired in 2004 by the Lagardère Group. Since then, it has been an imprint under Lagardère brand known as Hachette UK.
In 2004 Lagardère acquired Australian publisher Hodder Headline for Hachette Livre, who renamed it Hachette Australia.
In 2006, it expanded into the United States when it purchased Time Warner's book-publishing division, which was then renamed Hachette Book Group USA. Part of Time Warner's holdings was Australian independent publishing house Lothian Books, which was incorporated as an imprint.
