Can PowerPoint change the world? Maybe not, but the claim is that these eight presentations certainly did. The staple of advisory teams, boardrooms and classrooms has come a long way since the software was released in 1987. The pilot presentation prepared by its founders imagined how Christopher Columbus might have pitched his transatlantic voyage to Queen Isabella in 1942. Over the course of more than three decades, PowerPoints have been at the center of some of the most groundbreaking moments in history, including the unveiling of the first iPhone in 2007 (actually done in Keynote, not PPT), Elon Musk’s 2016 Mars announcement, and former US Secretary of State Colin Powell’s speech to the UN Security Council that made the case for the 2003 invasion of Iraq.
