BBC: Privacy bodies have welcomed Google’s decision to anonymise personal data it receives from users’ web searches.
“By anonymising our server logs after 18 to 24 months, we think we’re striking the right balance between two goals: continuing to improve Google’s services for you, while providing more transparency and certainty about our retention practices,” a statement from the search giant said.
It added: “Unless we’re legally required to retain log data for longer, we will anonymise our server logs after a limited period of time.”

Interesting… for some reason I’m fascinated by the idea of subliminal messages.
“The brain is open to what’s around it. So if there is ‘spare capacity’, in terms of attention, the brain will allocate that resource to subliminal activity.
“These findings point to the sort of impact that subliminal advertising may have on the brain.
“What this study doesn’t address is whether this would then influence you to go out and buy a product.” BBC
