Yahoo! Clues, a new beta service that lets curiosity seekers see what people have on their minds by allowing you to search the searchers. You can see and compare aggregate data — such as gender, location and income level — with graphs, detailed maps and other metrics telling you who’s searching for specific topics.
Check the Trends of [Microsoft] and [Apple]

For example, if you compare the queries [Microsoft] and [Apple], you’ll notice that Apple is much more popular than Microsoft.

Limitations of Yahoo! Clues
Yahoo! Clues is similar to Google Trends and Google Insights for Search. Unlike Google’s services, Yahoo Clues is limited to the US and it only shows information for the past 30 days.
You can start exploring Yahoo! Clues from a link in our Search result pages, or by going toclues.yahoo.com.
