WhatsApp is a popular messaging software that Facebook bought last year. It now has about 900 million users, according to the company’s CEO Reported.

WhatsApp CEO Jan Koum shared the information with Mark Zuckerberg last Thursday. The journey of WhatsApp started 6 years ago. It gained much popularity overnight because of its ability to text, talk and send videos. However, in the last two years, the number of users of WhatsApp has been growing at the fastest pace.

Last year, Facebook bought WhatsApp for ৮ 21.7 billion. Since then, WhatsApp and Facebook have started working on a joint basis. Earlier this year, David Weiner, Facebook’s chief financial officer, gave some positive hints about the future of WhatsApp. He said at the time that WhatsApp could be used for business purposes in the future.
