TV emphasising its difference and its production value compared to social networking. The things people do on social network sites are either worthless or have a value close to zero. Compare this to TV which is made by skilled professionals and has a high production value. If TV lowers itself down to the social networking space it will just fall into the noise of the web and lose its value amongst all the twittering and poking.
TV will always have a place as something people can twitter about in real time.
