As we mentioned in our coverage of Zynga’s fourth quarter earnings, mobile has been one of the fast-growing parts of Zynga’s business. On the company’s earnings call, CEO and founder Marc Pincus revealed that mobile users have grown five-fold to 15 million daily active users in 2011. That’s up from 13 million in December.
That’s an addition of 2 million users in the past month, and an addition of over 5 million users over the course of the quarter. In the third quarter, Zynga had 9.9 million daily active users for its mobile games.
