Facebook has reported quarterly revenue that beat forecasts but its profit fell 9 percent as the social media company sharply increased spending to boost mobile revenue and future growth.
Expenses will grow 55 to 60 percent in 2015 from last year, including an 82 percent jump in the second quarter to $2.77 billion, it added.
"We're investing in the next set of services and what will be future investments like Messenger, WhatsApp and Oculus," Chief Operating Officer Sheryl Sandberg said in an interview on Wednesday after the earnings report. She was referring to Facebook's two messaging services and virtual reality headset maker Oculus Rift, whose first product for consumers has yet to be launched.
Messenger has more than 700 million users, and the app has been downloaded more than 1 billion times on Android, Google Inc's mobile operating system, Facebook said.
