Software giant Microsoft has fired a fresh salvo in its war with search giant Google.

The company's revamped search engine called Bing aims to do to Google Search, what Google's Chrome aimed to do to Microsoft's Internet Explorer: weaken the dominance.

Bing: Bing brings a colourful user interface for users. It has a side panel bar that displays search with related and history links relevant to users' search terms. The serach engine features a different background image everyday. The search engine comes with a set of related services, including Bing Travel, Cashback and Maps for Enterprise. Bing focuses on four key vertical areas: making a purchase decision (Shopping), planning a trip (Travel), researching a health condition (Health) or finding a local business (Local).

Google: Google for long sports a cleaner and simpler looks. The search engine displays stark white page with a search box. The upper left corner of Google home page links to other Google services including email, Maps, Orkut and images.
