On December 1, 1990, a busy day in the annals of copyright history, copyright protection was extended to architectural works. In addition, the Computer Software Rental Amendment Act took effect, granting the owner of copyright in computer programs the exclusive right to authorize or prohibit the rental, lease, or lending of the program for direct or indirect commercial purposes. Finally, the Visual Artists Rights Act of 1990 granted to visual artists certain moral rights of attribution and integrity.
