The Stanford Technology Ventures Program Entrepreneurship Corner is a free archive of entrepreneurship resources for teaching and learning, including videos and podcasts of talks by successful entrepreneurs.
Many of the talks are by IT people. For example, Microsoft CEO Steve Balmer and Siebel Systems founder Tom Sieble spoke recently. Balmer spoke about the early days at Microsoft, the patience and hard work required of an entrepreneur, and the great opportunities open to Internet entrepreneurs today. That was in contrast to Siebel who spoke about opportunities in health care and energy, and asserted that the time for opportunities in IT is past. In a third lecture, neuroscientist and IT entrepreneur Jeff Hawkins reviewed his career, including the creation of the Palm Pilot and other portable computing devices and the founding of several companies and a research institute.
They have over a thousand two or three minute video snippets from the talks. You can search through them by key word or speaker. For example, there are 24 by Google's founding CEO Larry Page. You can watch one or two, or stream all 24 together.
