Hi Mike,
The idea I have for my podcast is to review stuff on a relevant stuff on a weekly basis and I just do not see how it would be possible to contact websites and companies like Youtube and get timely enough responses to receive permission to do something like this. Not suggesting I am just going to break the law because of the inconvenience, I am just hoping to get a better idea of how others do it.
i have spent a lot of time on iTunes going through their podcast directory and there are lots of podcasts that are doing exactly the same thing that I am trying to do (showing other people products and websites and videos). I understand that they too may not be completely complying with the law. Some of the podcasts are obviously small productions produced by one person while other are much larger and from companies like Revision 3.
