-                <p>The most successful way to fix an interview is for interviewers to audio record or hand write the responses of the person being interviewed. If the interview is recorded by hand, it is helpful if the writing is legible and clearly communicates the conversation because it may help solve questions about fixation.  Short hand that only describes excerpts from the interview typically are not enough to constitute fixation and copyright ownership. So please remember, if there is no fixation of the interview then no copyright exists in that interview.</p>

-                <p>Further, if you are being interviewed please be aware that you do not possess ownership over your responses in most situations. It is always best to briefly think about your answer before you respond to avoid the misuse of your words by others.  And if you truly don’t feel comfortable being interviewed by a particular media source, remember you always have the power to say no to doing the interview.</p>
+                <p>But just because an author employs either of these copyright alternatives, that doesn’t mean that they are completely free of legal issues. For example, imagine you’re an advertising designer for Virgin Mobile, and you need a photo of a pretty teenage girl for your latest ad. You find a photo on Flickr that is free to use under a Creative Commons Attribution license. You use the photo in your ad campaign and plaster the photo on bus stops across Australia. This is exactly what happened, and since the photographer was adequately credited and copyright issues were non-existent everybody lived happily ever after, right?</p>

             <p>Storytelling is increasingly used in advertising today in order to build customer loyalty. According to Giles Lury, this marketing trend echoes the deeply rooted need of all humans to be entertained. Stories are illustrative, easily memorable and allow any firm to create stronger emotional bonds with the customers.</p>
             <p>A Nielsen study shows consumers want a more personal connection in the way they gather information. Our brains are far more engaged by storytelling than by cold, hard facts. When reading straight data, only the language parts of our brains work to decode the meaning. But when we read a story, not only do the language parts of our brains light up, but any other part of the brain that we would use if we were actually experiencing what we're reading about becomes activated as well. This means it's far easier for us to remember stories than hard facts.</p>

             <p>Storytelling is a means for sharing and interpreting experiences. Peter L. Berger says human life is narratively rooted, humans construct their lives and shape their world into homes in terms of these groundings and memories. <strong>Stories are universal in that they can bridge cultural, linguistic and age-related divides</strong>. Storytelling can be adaptive for all ages, leaving out the notion of age segregation.
