Duration of Copyright (Is it too long?)

The duration of copyright depend on the nature of the work in question for example:

1.     Literary, dramatic, musical and artistic works = the life of the author plus 70 years.

2.     Sound recording = at least 50 years.

3.     Broadcasts = 50 years

4.     Typographical arrangements of published editions = 25 years

In my opinion, the copyright is created to protect and promote the right of author. It is also a motivation for anyone to create a new work. Thus the copyright supposes to last for a long duration according to the hard work of author. Under 4 categories above, I think it is not too long.
