About Google Video | Google Video Help
Our mission is to organize the world's information, and that includes the thousands of programs that play on our TVs every day. Google Video enables you to search a growing archive of televised content – everything from sports to dinosaur documentaries to news shows.
Just type in your search term (for instance, ipod or Napa Valley) or do a more advanced search (for instance, title:nightline) and Google Video will search the closed captioning and text descriptions of all the videos in our archive for relevant results. Click on a video title on your results page and you can view still images from the video and, where a transcript is available, short snippets of transcript text.
