Big Retailers in India are planning to start Hypermarts after having successfully launched smaller format retail stores.

Reliance, Aditya Birla and Tata’s Star Bazaar are focusing on large European-style hypermart roll-out while old hands like Spencer’s and the Future Group too are scaling up their hypermart formats. Hypemarket are the next stage in retail revolution for some brands. They will get higher margins, volumes and more brand recognition.
“The supermarts have already established brands, now hypermarts can levearge that brand recognition and create a captive customer in smaller markets. European style of hypermarket with roomy isles and white lights seems to be favoured by the new players in India”, says a marketing consultant attached to an Indian retail business house.

Why this will be successful in India, See this definition from Wikipedia,

a hypermarket or multi-department store is a superstore which combines a supermarket and a department store. The result is a very large retail facility which carries an enormous range of products under one roof, including full lines of groceries and general merchandise. When they are planned, constructed, and executed correctly, a consumer can ideally satisfy all of their routine weekly shopping needs in one trip.

This will be successful because, Indians like to take their shopping at malls as weekend outings for the family.
