VIDEO : NBCUniversal Goes After TV Advertising

NBCUniversal is seeking to change how TV advertising is bought and sold.
The media giant is set to introduce CFlight. It's a new TV ad currency that the company says will better take into account TV viewership of all kinds. This whether people watch shows live, on demand, or through a DVR.
NBCU say that CFlight will provide advertisers with a composite metric when they run ads on shows like "Will and Grace." The metric reflects when people watch on their own time.
