In 1985, when Wipro Consumer Care and Lighting test-marketed its now No 1 product Santoor in the Bangalore market, it had failed. Usually, if a product fails in the test market, the company does not extend it, either junk it or do a major revamp and do the retest. But in this case, it was different. The company was so confident that it went ahead and launched the product nationally. Now, Santoor brand has crossed Rs 1,900 crore in sales.
