Facebook (FB) is one of the biggest social networking platforms. It acquired WhatsApp in 2014, which surpassed 800 million users in April 2015. In September 2015, WhatsApp breached the 900 million user barrier. Mark Zuckerberg, Facebook’s CEO, announced that he’ll consider monetizing the service when the number of users crosses the 1 billion mark. This will give Facebook yet another opportunity to grow its revenue. On September 23, 2015, Facebook’s popular photo sharing app, Instagram, reached a milestone of 400 million users. Facebook currently has a market capitalization of $300.5 billion.
