Earlier quoted context omitted.
I would probably always pick non-personalized, as my assumption is that the less relevant they are, the easiest it would become for me to ignore them (assuming they are not more intrusive than the personalized ones).
This isn't a scalable solution. If the value per ad decreases, services will need to display more til the user generates enough value to support the costs they incur. If TV was able to cater ads to individual viewers then ad breaks would be a lot shorter.
Or they could sell the same amount of ads as they do now for higher prices. Which one do you think the company would pick?
The length of ad breaks is determined by what 'price' the customer is willing to pay in terms of their time.
