I have a collection of videos on my YouTube channel and most of my recent ones are about commerce and more specifically WebSphere Commerce. The commerce related videos are similar to what we would show to a customer in a meeting or at a conference but in a smaller scope and generalized.
Since YouTube decided to make my channel pretty ugly and harder to find things I attempted to arrange my videos in sections by content type – I hope this helps. If you are looking specifically for commerce only related videos then you can use this URL. The videos are really for educational purpose and most of my content is actually taken from the InfoCenter – which I think the development and documentation team do an outstanding job in making sure it is very comprehensive for marketing people, developers, and administrators.
