Copyright Protection: So many, why?
So many, why?
Why so many works and so many rights?
The history of American copyright law may be an answer.
In May 1790, the first Congress adopted first American copyright statute. It protected only maps, charts and books.
In 1865, photographs and photographic negatives were included.
In 1912, another technologically new expressive form, motion pictures, was brought within the ambit of law.
In 1971, sound recordings were added to the protected list.
In 1976, another technology of expression, computer programs, had begun to intrude the order of things.
In short, the enlargement of the definitions of “works” and “rights” are on account of the appearance of new information technology.
