The interesting thing is that alternatives to PowerPoint are actually easier than before. Does anyone know where the trend towards simpler presentations started? In the '90s, everyone went crazy with transitions, but even beyond that you had a more verbose format, with your usual headline + three bullet points format. These days it's often one phrase or even word per slide. Keynote and its more minimalistic design (or arguably feature set) was one contributor, but I think it started even before that.
