Always with a huge shortage of meaningful slots to place spots the expanding tv networks will be offering better service to advertisers and at reduced rates.  After reading an article in Antenna, in The Sunday Age, yesterday, it lead me to the headline conclusion.  Its all good for television, but man, the audiences have got to be getting tighter.  By maturity of the television market I mean the new digital licences are like a line extension of the original stations.  The segmentation will be greater and greater.
