The document discusses advertising spending and sales growth trends among Indian companies. It finds that when companies increased their advertising expenditures, they experienced higher sales growth. For example, Hindustan Unilever saw advertising expenses more than double from 2000-01 to 2007-08, and sales growth of 13.2% in 2007-08. Similarly, other companies like Bharti Airtel, Dabur India, and Cadbury saw advertising expenditures rise and sales increase in turn. However, some MNCs did not increase advertising as much as domestic Indian companies, and saw relatively lower sales growth. A study forecasts 9% growth for India's advertising industry in 2010, with key growth from digital media like mobile and internet advertising.
