Enters Public Domain in
Canada Sunday January 01, 2012
New Year's Day now marks public domain day, the day when new works enter into the public domain.
While Europe marks the entry of James Joyce into its public domain, Joyce has been in the public domain in Canada for the past 20 years, serving as an important reminder of the implications of the term of copyright. In Canada, the term is
life of the author plus 50 years, consistent with international law. In the U.S. and Europe, the term exceeds international requirements by adding an additional 20 years, meaning many works take two more decades to enter the public domain.

Copyright Term Extension
(Walt disney protection Act)
The Walt Disney Company lobbied extensively on behalf of the Act, which delayed the entry into the public domain of the earliest Mickey Mouse movies, leading to the nickname "The Mickey Mouse Protection Act". In addition to Disney, California congresswoman Mary Bono ( Sonny Bono 's widow and Congressional successor), and the estate of composer George Gershwin supported the act. Mary Bono, speaking on the floor of the United States House of Representatives , said:
Actually, Sonny wanted the term of copyright protection to last forever. I am informed by staff that such a change would violate the Constitution . ... As you know, there is also [then- MPAA president] Jack Valenti 's proposal for term to last forever less one day. Perhaps the Committee may look at that next Congress.
