The Kodak Theatre, which was the site for Oscar presentations between 2002 and 2012. Billy Crystal referred to the venue as the "Bankruptcy Theatre" at the 2012 presentations. As a facet of the camera company's demise, the Kodak branding had been removed in February of that year. In May, a new sponsor was announced and the auditorium was bequeathed a new name. On June 11, 2012, it officially became the Dolby Theatre.
