interactive video: Producing Interactive Video Available to Purchase

If you've been following this series over the last five months, you've read about the concept of interactive video and its use in training, about production standards and compatibility, about instructional design and authoring systems, about what people in the industry here and in America are thinking and doing. I hope that by now you're also thinking about doing a programme yourself, so I'd like to devote the last article of the series to some notes on making video interactive.
