In this video Copyright:” Forever Less One Day”, the author discusses the origin of the implementation of Copyright. In fact, the author says that the idea of copyright was first carried out by in United Kingdom; the purpose was to enable authors to have control over their works, and to avoid fraud. Concerning myself, I just knew from this video about Copyright that Copyright has expiration date, before I thought that the right of the author was unlimited. My opinion is that Copyright is a great thing insofar as it allows authors to survive from the work they have done; otherwise with the evolution of the technology, people would use others guys work as their own.
