When I searched www.blinkx.com for business topics, I found that blinkx also includes videos from Bloomberg, CNN, EuroNews, CBS, etc. Try searching blinkx for videos of interest to you and your classes. As always, it is important to evaluate each source.
To learn more about blinkx I checked the about page on its website and learned how blinkx receives its content:
"Using automatic spiders that crawl the Web, and through partnerships with 200 leading content and media companies, blinkx has indexed over 7 million hours of video content and made it fully searchable using speech-to-text transcription and visual analysis."
