Google currently has a cool experimental Search feature which provides a Timeline for search queries. All you have to do is write "view:timeline" before or after your search query in the Google search box. An interesting search query I've tried using timeline view was for Hosni Mubarak. The timeline clearly shows a rise in 1981 which as the year Hosni Mubarak became President of Egypt. The other even higher rise in the timeline is in 2005, that was the year when Mubarak was reelected as President of Egypt in a first ever multi-candidate election to be held in Egypt. This new experimental timeline feature in Google search is way cool.
