In the beginning was the Word. Now there's PowerPoint. It's used for weddings, warfare and webinars, for literature, lessons and law.

And, of course, to tell everyone that Q4 is going to be a lot more challenging than Q3. PowerPoint is probably the most successful piece of software in history - but do you know who invented it? Or why it's banned in American courtrooms? Or which Pulitzer Prize-winning novel has a chapter entirely in PowerPoint? At its heart, PowerPoint is about presentation, theatre and culture. About how to think, create and persuade.

And it's hated and loved in equal measure for reasons that tell us a lot about power and who gets to say what where. All of life is somewhere in a PowerPoint slide. Come inside to find out why.
