Here I want to introduce the radio program/podcast called This American Life. In it, the host Ira Glass and other reporters do an excellent job of exploring a theme or idea by interviewing people. Their production techniques, including source audio and music are a good example of creative story telling.
and a link to it’s youtube site, http://www.youtube.com/talwithiraglass
and another youtube clip of Ira talking about storytelling.
Also archive.org is, as the name suggests, an archive of audio and visual material online. It’s a good resource for material that is legal to use for your own productions.
