Here’s a Harvard Business Press article on how to give a successful TED talk, or any other presentation. There are several videos included to illustrate different points, and I thought that was pretty helpful.
“By now most people have heard the advice about PowerPoint: Keep it simple; don’t use a slide deck as a substitute for notes (by, say, listing the bullet points you’ll discuss—those are best put on note cards); and don’t repeat out loud words that are on the slide. Not only is reciting slides a variation of the teleprompter problem—“Oh, no, she’s reading to us, too!”—but information is interesting only once, and hearing and seeing the same words feels repetitive. That advice may seem universal by now, but go into any company and you’ll see presenters violating it every day.”
