Storytelling is an important part of any presentation. There's also quite a hype around storytelling these days; you see it used in all sorts of environments, from advertising to branding your own company. On the one hand, that's a good thing, since it shows that storytelling is on to something - it works. On the other hand, the hype could potentially cause people to turn away from it or ignore it, assuming that, as so many things that have been hyped before, it will be dead and replaced with something else in a few months.
Storytelling was also the main topic of the Presentation Zen Studio in Paris this year; but the participants agreed that there's more to it than just a hype. Storytelling is, in fact, a very very old technique and it won't become irrelevant anytime soon, even if (or once) the hype machine moves on.
