The United States enacted its first law regarding Copyrights 235 years ago on May 31, 1790. It was very limited in scope and had a 14 year renewal period, unlike today which is 70 years after the death of the author in most cases. There was also no Copyright Office at the time; the author had to register the copyright in the district court they lived in to protect their works. Its amazing to see how far copyright law has come and ever evolves, especially in the age of artificial intelligence.
