VIdeo search company SnapStream this week unveiled its new search tool, TV Trends. The new TV Trends utility tallies and graphs mentions of any term uttered on national U.S. television.

TV Trends users can enter up to five keywords, and gets back a graph showing you the relative frequency of mentions of those words on “mostly-news programs” on ABC, CBS, NBC, FOX, MSNBC and CNN. Graphing capabilities let the user zoom in and out to look at the past day, week, month, year of network TV mentions.

TV Trends graphs can be embedded into users’ websites, to graphically display trending topics for readers.

Current “hot” and “cold” terms of the day are available for view at the TV Trends site. It is also possible, at the TV Trends site, so check out excerpts of stories at selected points along the curve. Users can filter the results by network (look at mentions of “Obama” on Fox (yuck) or MSNBC) and by genre (show me mentions of “Palin” on comedy programs).

SnapStream TV Trends is powered by SnapStream’s TV recording and search technology, which enables organizations to record “LOTS of TV,” and then search within those shows for mentions of the terms relevant to their brand. A cross between a DVR and a search engine, the SnapStream hardware allows recording of up to ten video streams at once, up to thousands of hours of TV, and then search inside those recordings.

Current SnapStream TV Trends monitoring users include E!’s The Soup, XM Radio, NBC, Current TV, the U.S. Senate, University of Southern California, University of Texas, City of Austin, and the City of Chicago.
