AACS LA (Advanced Access Content System Licensing Administrator) is the body that develops and licenses the AACS copy-protection system used on the HD DVD and Blu-ray Disc high-definition optical disc formats.


The AACS LA consortium was founded in 2004 consisting of 8 companies which are Intel, Microsoft, Panasonic, IBM, Sony, Toshiba, Warner Brother and The Walt Disney Company.[1] The AACS standard was delayed 2 times, the first of which were caused by development issues,[2] then the second from an important member of the Blu-ray group expressing concerns.[3] At the request of Toshiba, an interim standard was published which did not include some features, like managed copy.[4] On July 5, 2009 the license of AACS1 went online.[5]
