iPod's contribution to online education and Podcast

One of problems of online education is connectivity. Unfortunately, infrastructure is still very primitive, and connectivity isn't that great. Also "broadband" isn't really broad; we still cannot watch video comfortably. For example, if you watch streaming video at Stanford Graduate School of Business, View from the Top Speaker Series, video gets interrupted quite often. We even have problem listening to audio sometimes. Podcast was introduced in this environment in order to address the problem of connectivity by downloading data at once instead of streaming it. There are literally tens of thousands of Podcast shows today, and there are Podcast shows related to online education as well such as Technology and Learning. But Podcast's bigger contribution to online education is to address the problem of connectivity. As I mentioned already, connectivity is not that great. The infrastructure has improved dramatically since early 90s; however, we are certainly not at the point which we can comfortably access audio and video content on the internet, which is the platform to enable online education. Podcast addresses this problem; it's a very simply solution, but Podcast makes lecture videos and audios much more accessible.
