RE: Facebook Spends $1.0B on App Company according to this article: https://www.reuters.com/article/2012/04/09/net-us-facebook-idUSBRE8380M820120409 , they have 30 million users since Jan. 2011 (amazing).
"This is an important milestone for Facebook because it's the first time we've ever acquired a product and company with so many users," Facebook CEO Mark Zuckerberg said in a blog post. "We don't plan on doing many more of these, if any at all."
I believe this is a smokescreen. This industry, like others, does alot of convergence and consolidation.
