I have a question regarding copyright-laws.
I want to write an Android App. In this app I want to use an Audio-Clip of a Simpsons-DVD, that I bought. This audio-clip is about 20 seconds long.
This particular section that I want to use can be found on Youtube many times, but instead of just using it, I want to ask you. The app should be for free and I don't want to include advertisements.
Am I allowed to use a short clip? If not, who do I have to ask, to get the permission? Who is the actual owner of these things?
