Yahoo Clues

Yahoo released a new tool today called Yahoo Clues, which displays demographic trends related to popular searches. It also includes a "search flow," a look at the previous and next search terms used.  At present, Yahoo Clues only tracks the most popular topics, but "Yahoo said they hope to expand the number of terms included over time," according to Search Engine Land.

Here's a brief description from Yahoo:

Yahoo! Clues lets you explore how people are using Yahoo! Search. When you enter a word or phrase in the [Find Trend] field and click Discover, you’ll see information about that search term’s popularity over time, across demographic groups, and in different locations.


You can also enter a second search term in the "Compare With" field. This will show you information on both search terms, side by side.
