I have noticed a trend, probably because You Tube makes it easy to do, of adding commercials into keynotes, staff developments, presentations, etc.
For instance, I have added Apple's classic "Think Different" commercial in a variety of trainings over the years.
Recently, my Superintendent added an ad into a presentation to administrators about constructing an airplane in flight.
I have also seen the famous "Elevator" comercial used in several presentations, even though I had never seen it until Kevin Honeycutt showed it to me.
So the discussion here is:
What commercials have you seen added to presentations about technology/Web 2.0/ 21st Century skills?
