Let’s imagine you got your animation just right — you tweaked the speed, set the animation events, etc. You also added a series of simultaneous and sequential animations to the same slide object — so that it fades and wipes at the same time — then it grows in size, stays on screen without animation for a requisite amount of time (delay) — and finally the object exits using a simple fade animation. Now, you need to apply the same animation to 50 other slide objects within the presentation! Typically, you may have to spend an enormous amount of time for such a repetitive task, manually applying the animations so many times! That was before the introduction of the new Animation Painter feature, introduced in PowerPoint 2010, which works with animations exactly in the same way as Format Painter option works with slide objects.
