App's users send 300 billion messages per month.
WhatsApp, the creator of the hugely popular cross-platform mobile chat application, has apparently been locked in talks with Facebook regarding a potential acquisition. TechCrunch sources revealed the potential purchase but didn't get any information about a price or how advanced the talks may be.
Since its launch in 2009, WhatsApp has proved to be popular among BlackBerry, Android and iOS users due to its depth. It delivers text messages, images, audio and video messages, as well as a group chat option. The application, which doesn't feature any advertisements, boasts around 100 million daily users, with the app itself having a presence in 250 countries. It's currently free on Android and requires a small fee for iOS users. It's remained on the top-selling/downloaded app position in a majority of regions for months.
WhatsApp sees users collectively send 10 billion messages per day, which equals 300 billion messages per month. The latter figure is what iOS' iMessage managed to accumulate over a whole year.

How about Blackberry?
This is one of the reasons for its success. If FB buys it, there you go with a ton of "featured" texts, your personal stuff and files being forwarded to third parties and boom! WhatsApp fades into oblivion.
It's not free, it is a free trial. Go to Settings -> Account -> Payment info and you will see the expiration date. Android users will probably have to start paying per year.
The hope of a buying company is that the new advertisements aren't annoying enough to offset the inconvenience of switching (with all your friends) to another place for chat.
Except when that company is Facebook and they need to climb back from a deep stock price hole.
Also why would I want facebook to spy on my text messages?
Don't run a good thing. Start Charging those Android bums. Not fair I had to pay $1 for it and the Android users get it for free.
I wish everyone would just use something that's cross-platform compatible, like Skype. Oh well, maybe if Facebook acquires WhatsApp it'll become natively usable on PC, even if it's only browser based. I'd much rather have it in a browser than inside an Android emulator.
If Facebook's psychopath CEO buys it, I'll uninstall it...
It's only free for the first years, after that, Android and Win8 users pay too...
Congratulations. Want a medal?
