San Jose State University have an online version of presentations that address a variety of topics that you can view from the comfort of your home. The topics are diverse and touch on many of the topics that have been introduced to us via our classes.
The presentations are in Real Player format but they are embedded on a web page. There is a captioned version available as well as an audio .mp3 format and the video mp4 or m4v (iPod format).
I do have to tell you that the video download huge. To download the Community Outreach video was 680MB so you might want to view online. You should have a broadband or cable Internet connection to comfortably view or download the presentations.
You have the option to subscribe to the Colloquia via RSS or iTunes. Most of the presentations are about 30 minutes to an hour. It is a neat way to keep up with topics in the industry.
