Hello,
Here's a fun visual essay by Xaquín G.V. in collaboration with Google News Lab. The premise is that many people search for information on how to do everyday activities. From fixing things around the house, to cooking, to getting rid of hiccups. There's some neat (albeit vague) interactivity to see how search is different across different demographics.
How did we get anything done before search? :)
