WhatsApp, the instant messaging service which was acquired a couple of months ago by Facebook, now has 500 million active users. Today, WhatsApp co-founder Jan Koum wrote a blog post thanking all the users. Here's what he wrote -
Thanks to all of you, half a billion people around the world are now regular, active WhatsApp users. In the last few months, we've grown fastest in countries like Brazil, India, Mexico, and Russia, and our users are also sharing more than 700 million photos and 100 million videos every single day. We could go on, but for now, it’s more important that we get back to work – because here at WhatsApp, we’re just getting started.
