Flipkart has been selling Hindi and English language ebooks since November 2012 using their own proprietary format. Readers can access the ebooks via Android, iPhone, Windows, and iPad apps as well as a recently launch web app.
The retailer boasts that they stock 250,000 titles at the moment and plan to increase that to a million titles by the end of the year. They also expect to add more local languages in the next few months, including Marathi and Bengali.
Flipkart is estimated to have a 40% share of the Indian book market, but there is no information on their share of the ebook market. They're competing against Amazon, Apple, and Google, all of which have launched an Indian ebookstore over the past year.
