The number of people using Facebook messenger application has crossed 800 million, taking the lead as the fastest growing social networking site of 2015.
Facebook reported 500 million monthly active users in November 2014, 600 million in March 2015, and 700 million in June.
These numbers doesn’t include WhatsApp and Instagram, both which Facebook owns.
“2015 was a year when we made significant improvements to how we enable people to communicate. Among other things, we made Messenger blazing fast, we introduced video calling, the ability to customize conversations with colors, nicknames and emojis, and with Businesses on Messenger, we introduced a new way for businesses to engage their customers by providing them with a delightful, personal experience. We rolled out the ability to send and receive money to friends right from conversations, launched Messenger Platform for expression apps, and updated the way you can choose to share your location. We added helpful information at the top of new conversations so you always have the context of who you’re talking to if it’s not a Facebook friend, and with Message Requests, we built the foundational step of enabling you to find and talk to anyone. We also made photo sharing with friends easier than ever with our new feature Photo Magic. Additionally, we started testing M, a digital virtual assistant, and closed the year by launching our transportation platform with Uber. It was a busy year! We created all these experiences with a mindset of helping hundreds of millions of people manage their daily interactions with people, businesses, and services more seamlessly than ever.”
