What I find even more mind boggling is that despite all that tracking, advertising still misses the mark by a mile. I regularly see the same ad repeated 10 times in a row while also being completely irrelevant to me. Meanwhile I also frequently miss stuff that would be relevant for me and that should be covered by ads (e.g. movie releases, I might pick up the first trailer, but completely miss when the movie actually hits cinemas).

For the money and effort spend on ads you’d think they could do a lot better than what they are.
