Google has launched their Google Video Search, which lets you search through what appear to be transcripts from television shows for any terminology you woudl typically use in your Google searches.

For example, click here to search for "blogosphere" and you can click through and see where the term was used on television in recent weeks.

Cool stuff, especially if you're looking for coverage and use of key terms or names:

• Enron
• hubris
• tsunami
• "snow storm"
• "Academy Awards"

You get the idea.
