I had posted some similar threads and received many great tips and suggestions. Now it seems that I've got addicted about it. Since I'm still a newbie in this field, today's topic will be mainly focused on video presentation online. Last time I tried record my computer screen to make tutorials and publish on my site. This time I find PowerPoint can also do the same thing. I mean, you can make presentation with PowerPoint then release it online as the same as videos do. Well, I've no idea about it untill I find one article called "How to Convert PowerPoint to Video for Free" at eHow.com. From its point of view, PowerPoint to video can be another inspiration of online marketing. In fact, it's rather easier and more popular for businessmen because PowerPoint gets many more users all over the world comparing with screen recording software. And my question is, can PowerPoint video presentation online really make business opportunity? (I'm preparing to have a try)
