Since when are search results personal data?

  They are affected by personal data. E.g. if you performed a search, and your friend next to you performed the same search and got different results there is probably no way Google could give a concise or exact explanation as to why your results were different.

  I would guess personalized search results went mainstream on 2005 or so, as Google became popular, but perhaps some of the portals Google replaced (ask Jeeves and Yahoo) had personalized results before that
