A family of Microsoft presentation graphics products that offer tools for creating presentations and adding graphic effects like multimedia objects and special effects with text.
I'm not sure why this effect was removed from the user interface, but it's still supported; you need to use a little VBA to get at it. This macro will apply the NewsFlash effect to all currently selected slides:
Sub NewFlashMe()
With ActiveWindow.Selection.SlideRange
.SlideShowTransition.EntryEffect = ppEffectNewsflash
End With
End Sub
