Google released a browser extension, Google Related, that brings you relevant information to you when you browse web pages. It is available as a Chrome extension and Google Toolbar for Internet Explorer.
Google Related: Find Relevant Map, News, Images, Videos
Once installed, this extension seeks to find out information that you may be interested in when browsing web pages. These data are shown on a buttom bar. For example, when you read the web page of a restaurant, Google Related may show you the Google Map location, restaurant reviews and news. I ran a trial on the White House official site. You can find a white information bar at the bottom of the page. Let’s have a closer look of it:

The information bar has several boxes. Clicking on the Map box shows a map of White House and its opening hours. You can see reviews and related places on Google Maps.

You can choose to hide this bar for the page or web site you are viewing.
