WhatsApp handled 7 trillion messages in 2014 - nearly 1,000 for every person on the planet

"The time users are spending on messaging services has encouraged investors to value them highly, even though it is not yet clear how some of them will make money—much as happened with the rise of Twitter and with Facebook’s original service, its social network. WhatsApp handled more than seven trillion messages last year, about 1,000 per person on the planet. In Britain users spent as much time on WhatsApp as on Facebook’s social-networking app, according to Forrester, another research firm. In China subscribers to WeChat are estimated to use the app for about 1,100 minutes a month on average."
