A great presentation is more than just a vehicle for delivering facts and information. You know this because when you've witnessed a great one you've walked away entertained, refreshed, and inspired.
Chances are you'll remember certain things about it that really resonated with you, and you'll find it much easier to retain the content because it was offered to you in such a unique way. Great presentations are a combination of carefully chosen visuals, concisely plotted information, and often a very simple approach meant to connect to an audience rather than overwhelm them with bullet points and embedded media. In such presentations, everything has a purpose and place.
