In his TED talk, John Bohannon says that “bad powerpoint presentations are a serious threat to the global economy”. He estimates that:
Each day $250,000,000 (USD) is spent on presentations, assuming each presentation is ½ hour long, with an average audience of 4 people that have an average salary of $35,000 USD.
Each day there are 30,000,000 presentations created
¼ of presentations are a total waste of time
$100,000,000,000 (USD) is wasted globally on presentations each year
I don’t know how accurate his numbers are, but I do know that I feel blessed when I see/attend a great presentation, and bored and antsy when I”m watching/attending a bad one.Which got me thinking about why a lot of presentations are so bad, and only a few are good. Having been a presenter all of my adult life, I’m dedicated to, and fascinated by, the science of giving a great presentation, and therefore decided to make that my next book: 100 Things Every Presenter Needs to Know About People.
Score a free copy of the book — For this book I am including “Stories From The Field” which is a collection of tips and stories from YOU. I’m asking people to send me their presentation tips, techniques, good, and disaster stories. If I use the story or tip you send me in the book, then you’ll get a free copy of the book (due out in May).
So if you have stories, tips or techniques email them to me at: email@example.com
