Every year Google puts out a year-end Zeitgeist report highlighting the top searches and rising searches for the year. They just released the data for 2007. It's interesting to see what people are searching for and how it changes from year to year. Here's the top 10 rising searches on Google for the year:
8. second life
10. club penguin
6. club penguin
10. anna nicole smith
The showbiz search data is also kind of fun--it shows how searches for celebs correspond with their other news, events, and offline publicity.
