ads are pretty worthless if there is no data to back them up. Ads need to be targeted and they need to know about clicks, what they got and so on.
How do you think advertising works?
I call shenanigans.
I have a television that isn't connected to satellite or cable, but is just "free to air" or Freeview as it's called here in the UK - I have an aerial on the roof that delivers the signal to my television.
There are ads on all channels (except the BBC). The advertisers know nothing of my viewing habits, and nothing about me personally, yet they still appear. They only know that if I'm home during the day watching a television show, an advertisement for lawyers might hit the mark as I might be someone who was harmed by someone that can be sued (hence their offering).
When I buy a magazine, there are ads all through it - however, I don't have to give any information about myself at the news agent.
The point is that although advertising is made better with detailed information about me (the target for the advert), it isn't nullified (as you've both stated) when that data isn't there.
