I was trying to give you quick summaried, multiple points of targeted advertising in my reply. Others who replied have taken the fishing example and pointed out how detailed targeting could go for that specific case.

And the particular case that you are now picking on could be argued as a corner case that captures both segmentation and individualisation at same time.

Anyway, the point has been made about why individualisation could be a tricky curve by me and the others. Choose whichever example(s) gives you the best rationale.
