This presentation describes the various types of educational software which are on the market now or which will be published in the near future. First the producer must focus on issues like: Who is going to use it? What do they learn from using the software, and how do they do it? Secondly the producer must develop the product, and deal with all the practical problems from design to marketing. As very few producers reach the stage of financial profit, the presentation offers no advice on how to invest your fortune.
