PowerPoint karaoke

PowerPoint karaoke, also known as battledecks or battle decks, is an improvisational activity in which a participant must deliver a presentation based on a set of slides that they have never seen before.

PowerPoint karaoke originated in October 2005 in Karlsruhe where engineering students would download a random slide deck and present it during a party.

was invented by an improv troupe known as Senseless Death in 1995, where a performer was asked to leave the room, while an MC and the audience quickly constructed slides, including graphs and acronyms.

British philanthropist and raconteur Senor Cucumber used Power Point Karaoke as a tool to convey his economic principles during The Impossible Lecture in Skipton, England in July 2012.

In 2025, Minna Taylor and Nathan de Groot will host Slide Slam: The World Championship of PowerPoint Karaoke in Amsterdam on April 7.
