I wish the defense and corporate sector wasn't so enamored with conveying information through slide based presentations. I do my best to create short (1-3 pages) technical reports with informative graphics.
The good news about PowerPoint is that you start from nothing and have a slide presentation in five minutes.
The bad news is roughly the same.
Politicians still don't use slides. It would be more interesting to retrieve an actual business presentation from the 1940s.
