The feedback on most presentations is usually that it could have been shorter, more to the point. So, if you can pretty much say anything in 10 minutes, why do people study for years to get an academic degree in something?
The answer: most business presentations are conducted in front of an audience which is pretty familiar with the subject. The venture capitalist has seen thousands of startup pitch presentations, the retired angel investor has interviewed and met thousands of candidates for specific positions, the strategic acquirer knows the limitations of a certain technology, the CEO has a pretty decent understanding of the market she is operating in.
So all these presentations can skip all the background and dive straight into the one thing that is new, that is different.
