Might seem a bit strange, but Kodak bailed out of a naming rights deal with CIM Group, which owns the place, and CIM asked the Academy of Motion Picture Arts & Sciences not to mention Kodak during Sunday's telecast. Instead, they're refer to the theater as being part of the "Hollywood and Highland Center." From THR:
It is not clear when CIM will actually strip the Kodak name off the theater or ask the City of Los Angeles to change the many road signs and markers in the area that point people to the theater. CIM has engaged Premier Partnerships to search for a new naming rights sponsor. However the process is complicated since a major brand would not want to pay $50 million or more for their name to be on the venue unless they are assured the Academy will keep the Oscars there for the term of the deal. That is yet to be seen.
