Sonny Bono Copyright Term Extension Act

The Copyright Term Extension Act (CTEA) of 1998 extended copyright terms in the United States. Since the Copyright Act of 1976, copyright would last for the life of the author plus 50 years, or 75 years for a work of corporate authorship. The 1976 Act also increased the extension term for works copyrighted before 1978 that had not already entered the public domain from twenty-eight years to forty-seven years, giving a total term of seventy-five years. The 1998 Act extended these terms to life of the author plus 70 years and for works of corporate authorship to 120 years after creation or 95 years after publication, whichever endpoint is earlier. Copyright protection for works published prior to January 1, 1978, was increased by 20 years to a total of 95 years from their publication date.
