Copyright hasn’t stayed the same since it was created. Here are some of the most notable laws that have affected copyright.

Canadian Copyright Act (Originally established in 1832)

The Province of Lower Canada granted residents copyrights with the original CCA to encourage the emergence of culture in a developing nation. This was re-established in 1921, and covered everything from architecture to newspapers. The act was reformed in 1988, 1997, and again in 2012, most recently focusing on the public’s rights in reproducing legally obtained materials or piracy.

Cyber Intelligence Sharing and Protection Act (CISPA, 2011)

A proposed United States law that would allow sharing of Internet traffic information between the government and technology and manufacturing companies to investigate cyber threats and ensure network security. If CISPA becomes a law, companies such as Facebook or Google would have grounds to distribute personal information to the government if copyrighted material has been used by someone.
