At what point do TV retings become obsolete? Network execs still make their decisions on what shows to air, what shows to cancel, and when to air them based on the ratings they get, and the share they get for that particular time slot, but who still watches TV that way? With Tevo's and the internet, people can watch whatever they want to watch, whenever they want to watch it. Winning a time slot doesn't seem to really mean that much anymore. I would imagine Nielsen's ratings are becoming less and less representative of how much a particular show actually gets watched. A better indicator would be how much a show gets Tevo'ed, or how many people are downloading its torrent. And never mind trying to sell ads based on ratings; when was the last time you watched your favorite TV show with commercial interruptions? So why do networks still care about ratings?
