San Francisco: Facebook-owned smartphone messaging service WhatsApp has hit the billion-user mark, according to the leading social network's chief and co-founder Mark Zuckerberg.
"One billion people now use WhatsApp," Zuckerberg said in a post on his Facebook page. "There are only a few services that connect more than a billion people."
Google's free email service, Gmail, is the latest of the Internet giant's offerings to crest the billion-user mark, chief Sundar Pichai said Monday during an earnings call.
The ranks of people using WhatsApp have more than doubled since California-based Facebook bought the service for $19 billion in late 2014, according to Zuckerberg.
"That's nearly one-in-seven people on Earth who use WhatsApp each month to stay in touch with their loved ones, their friends and their family," the WhatsApp team said in a blog post.
After buying WhatsApp, Facebook made the service completely free. The next step, according to Zuckerberg, is to make it easier to use the service to communicate with businesses.
Weaving WhatsApp into exchanges between businesses and customers has the potential to create revenue opportunity for Facebook.
Recent media reports have indicated that Facebook is working behind the scenes to integrate WhatsApp more snugly into the world's leading social network by providing the ability to share information between the services.
