Combined answers from the Microsoft Community forum to the important question: "What's the maximum number of slides allowed in Microsoft PowerPoint?"

"Every slide is identified numerically by a Long number, meaning that the theoretical maximum is around 2,147,483,648"
"Personally, I make it a rule never to include more than 10,000,000 slides in a presentation. One slide a second is about all people can absorb at best, and very few audiences will sit there and absorb information at that rate for half a year."
