Here is example of a college using a vodcast (a video podcast), to help them solicit prospective students. They've posted this to YouTube so whenever a potential student does a search for Franklin College they'll receive this video as part of their results:
This session you will have the ability to go into as much depth as your curiosity (and time) allows. There is basic, elemental information available, as well as advanced information, instruction tutorials, and text directions for you to recreate and duplicate what these models show you. Similar to the distinction I made with Podcasts about the ability to simply use this tool, as opposed to creating videos yourself, please remember that I try to give you more information than you can digest with the hope that you will revisit these sessions in the future when the need (or desire) arises.
Good luck, have fun, and keep an eye on the clock.
