CTEA (1988) extended them to life of the author plus 70 years for personal registrations and for works of corporate authorship to 120 years after creation or 95 years after publication, whichever endpoint is earlier. Obviously, the estate keeps the rights after the author's death in the first case, the corporation in the second.
Yeah, not to mention that illegal distribution of certain telecasts also infringe on other rights, like trademarks.
I think the whole thing is very draconian though. Copyright was supposed to reward and entice creation, but the other element (letting items fall in the public domain) was also a crucial part to the benefit of society as a whole.
The system is too broken now, and it's likely to get worse than better.
