Since being released in August 2011, Facebook Messenger has achieved outstanding growth. For instance, the app had 700 million users in June 2015, 600 million last March, 500 million in November 2014 and 200 million in April of 2014.
According to Nielsen, Facebook Messenger was the fastest-growing app of the last year. Now, it seems like only a matter of time before it surpasses the 1 billion user mark, perhaps even doing so before its fifth birthday late this summer.
What's sobering—if you are a competitor such as Yahoo, AOL or Twitter—is that Facebook Messenger hasn't been monetized with advertising.
Comparatively, it took Facebook's flagship Web/mobile platform about eight and a half years to get to 1 billion monthly users, which occurred in September 2012. In November, the Menlo Park, Calif.-based company said it exceeded 1.5 billion monthly users.
During the first three quarters of 2015, Facebook garnered $11.4 billion in ad revenue.
