How long does it take to watch a TV show for it to be considered "watched" by the Nielsen rating system?
I’ve always wondered how long it took for me to watch a TV show for it to be part of the Nielsen rating system. For instance, if I’m just channel surfing and I just catch a minute or two of CSI: Missouri, does it count? Or let’s say I watch every minute of Japan Idol except for one, does it count? How long does it take? And how do I know if my television actually transmits this data (since it’s pretty old)?
