Suppose I attend few interviews and whatever interview question and answer I can recall I put in my blog. Now these interview question and answer will be copyrighted to the companys by default ? or this material will be in public domain that is anybody can reuse ? I see many websites who put interview question,placement papers of companies, claiming copyright on these placement paper as well , however this placement paper does not belong to those websites, they belong to the companies who has prepared them. Please share your opinion on this.
Once it's in a tangible form (such as written down or recorded) it's copyrighted. You can't just use it if it's someone else's material.
You recall something that is said and decide to write it later? That's absolutely fine. Recording a fact and news reporting is open to a bit of freedom as far as copyright goes (so no-one can try and cover up a story). Here's a scenario - I give an off the cuff speech to an audience and someone writes it down word for word - if I go and write about what I've just said, even though it's now in a tangible form created by someone else, would I be committing a copyright violation? I suspect not. That would be absolutely absurd!
I think it is entirely dependant on the venue in which the interview is conducted. If its at a public conference, it should be free game. If it's a private interview conducted (like for example, Entertainment Tonight interviews Brad Pitt or something like that), then it would be copyrighted.
I think we're getting our copyrights and confidentialities mixed up here. If Brad Pitt gives an interview to ET and someone decides to write on their blog "Last night on Entertainment Tonight Brad Pitt said the following....." then that's really not a problem because it's a statement of actual events unfolding - a record of developing news like I said.
While that is true, it also doesn't mean that you would be able to copy the whole interview, aired on the show, verbatim and post that on a blog. Pointing out certain answers and commenting on them, would be fine though.
