Times have changed very much, so has the value of time. Back in the old days people wanted to hear the whole story about something before committing because they had the time to. As time goes on that luxury of time is lost, so all the details of something can be left out.

If you can catch someone with three words, why say twenty? Details today are not as needed, people only want to hear the outcome. Sometimes when pitching a product idea a investor doesn't want to hear about the product that much, they want to hear about the money they can make. Approaching an investor with the ability to describe your product in three sentences and moving on the the profit part can be all you need.

Think of the most complicated piece of technology you have and look its box and read its description. Then find an old version of that product and look at how long its description is. As technology improves , the need for complicated explanation of how they work decreases.    

I personally think the simpler the better, because it leaves all of the unneeded extras and visuals out. It allows you to know what your getting and what it does. Some people appreciate that extra info and functionality, so keep it there. Just don't wrap the core idea in all of that wrapper.
