CNN.com also uses audio slideshows to generate content.  One example with some added video would be this emotional story:

The story is mostly told through images the photographer took during wartime.  The photographer’s emotional story is dubbed over the photographs, so that the viewer can see what he’s talking about.  Occasionally, video of the photographer is spliced in.  The photographer’s story is a good choice for a photostory, because he is very knowledgeable about the pictures and the pictures are compelling.  He is an excellent photographer who took visually interesting pictures.  Hearing him describe what he saw and did while looking at the pictures adds value to the story.

Here’s an example of a CNN.com slideshow without audio:

http://www.cnn.com/2011/10/06/us/us-occupy-protest/index.html 
This story would have made a good audio slideshow.  While the images are perhaps easier to access in this form, I think the story loses depth when sound is omitted.  The pictures each have some explanation provided in text, which could have easily been recorded into an audio file.  It would have helped explain who the protesters were, and why they’re protesting.  The text minimizes the issue and maximizes the imagery.

Over all, audio slideshows can be used to maximize the efficiency and entertainment value of a story.  There are times when a story is not visually conducive to a video but still has related imagery that has appeal, and in these cases, an audio slideshow can be very useful.  Examples of this would be pictures from Mardi Gras or the scene after a major storm.  CNN.com utilizes this technology, although perhaps less so than they should.
