I found an interesting and educational article, which describes how to do storytelling the right way. Storytelling is a means to market, or introduce yourself as a business to potential partners or customers. By telling stories the right way, you involve the listener in a dimension they can relate to. Combined with images and video to deliver your story, it may be a powerful combination.
Storytelling is widely used when crowdfunding a project, but are also widely used, when Apple, Microsoft and other large companies run ad-campains.
