I believe that the blending of video, email and Interent sites is slowly happening – Google has just announced their move to a video “adsense” service and the growth of sites like youtube is fantastic.
I did a small experimental video a few months ago and it is still getting a few visitors although I have not linked it anywhere (except here) www.Nizas.com/video
My plans are to make a lot more use of all video techniques and to present short informative clips of all places and properties.
