In this modern era, the first step to start a business would be to get your URL registered. If you don't do that, you might end up as another Airtel.
Open any browser and type in "www.airtel.com" in the URL field.
Surprised!!! Well its not the fault of the Browser.
Actually Vodafone had bought this URL from some Swedish company (they call this acquisition - a good business trick) and now anyone wanting to see the Airtel home page would be taken to its competitors home page.
... and I think, to avoid legal issues, cleverly they aren't showing the Indian Home page of Vodafone
