The one downside of a powerpoint presentation is that it may inform, but it doesn't inspire. The following advertisement discusses Volvo's steering technology. It could have very easily been a powerpoint slide showing how consistent Volvo's steering is vs. other steering technologies.
But a STORY… particularly one conveyed VISUALLY… conveys more than 1,000 powerpoint slides ever could. A powerpoint informs, but a story can LEAD people to change their minds and take action.
