In 2006, the NFB marked the 65th anniversary of NFB animation with an international retrospective of restored Norman McLaren classics and the launch of the DVD box set, "Norman McLaren – The Master's Edition". The NFB budget has since been cut again. The six-storey John Grierson Building at its Montreal headquarters has been unused for several years – with HQ staff now based solely in its adjacent Norman McLaren Building. In October 2009, the NFB released a free app for Apple's iPhone that would allow users to watch thousands of NFB films directly on their cell phones.
