The TEDTalks series featuring talks by Al Gore, David Pogue, Tony Robbins, and others at the Technology, Entertainment, Design conference can be searched for words and phrases with the help of PodZinger's video search technology.

The popular Rocketboom video blog reached a point where it needed a more robust search feature, and partnered with PodZinger to fulfill that function.

The podcast search engine just added video podcast search to its existing full-text podcast search service online.

Haven't test-driven it yet, but reviewing product features, it looks like PodZinger's ability to use voice recognition to help users search for podcasts is state of the art.
