How multimedia is like a rock
If you just looked at a rock, days later you’d be hard pressed to remember any important features about that rock. But if you got drilled in the head with that rock, picked it up and felt its surface, used your tongue to sample a taste, and sang some silly "rock" song about it - you sure would remember a whole lot more about that stupid rock.

THAT is multimedia.

In fact, informing your customers by flooding their senses increases their ability to understand by 50%, their ability to retain information by 60%, and your ability to persuade by up to 70%!
