Finally found an article on Narrated Slideshows

Although mainly technical, I have finally come across an article about this form of online journalism.

The article does well at stating the positives and negatives of this form, especially the difficulties that face creating one. This could be the reason why many tend to disregard this form for representing news, (as stated in a previous post by Ian Mayes). It simply takes too long to create, and where urgency is needed in news, this is an obvious flaw.
