Nielsen is launching Twitter TV Ratings, the first measure of the total activity and reach of TV-related conversation on Twitter—to help identify who's really engaging in real time and to better target ads.

The new ratings will measure activity—the number of people tweeting about television programs, and reach—the number of people who actually view those tweets.

This new measure comes just days after Twitter released its public S-1 filing, showing fast revenue growth, but a lack of profitability. This new ratings system could help Twitter grow its revenue in one key area: partnerships with traditional media companies, which is an area that Twitter said in its S-1 filing has promising growth prospects.
