According to Head of Facebook India Kirthiga Reddy, companies have increased their expenditure on online advertisements, which is now growing at 25 percent year-on-year. With an increasing Internet population, including the smartphone users, in India, Facebook is expected to post growth at the same pace in the near future. However, sustaining the growth will not be that easy.

As WSJ in its report points out, the social networking website has cater to millions of Indians still using the feature and low-tech phones. Moreover, it has to make its platform more accessible to the local developers to boost its ecosystem. If Facebook's model succeeds in India, it could apply same in other emerging markets such as Indonesia and Brazil. Facebook has definitely taken a lot of measures to make its services popular in the country. It recently rolled out support for Hindi and seven other Indian languages for its feature phone app.
