Primary Channels Are Being Cannibalised
 

Commercial free-to-air TV networks are calling on advertisers to cut them some slack over figures that appear to confirm fears that audiences of their primary channels are being cannibalised by new digital channels.

Some media buyers are delaying judgment over the double-digit declines in audiences for Seven, Nine and Ten's main channels until after Easter, when they will have at least nine weeks of the ratings period to review.

well what do they expect when they heavily advertise a show and then axe it weeks later? Also when they set their target's too high for new shows and get axed because they don't get the target?
