Low-key, underground photo-sharing app Instagram went mainstream on Monday, as the year-old startup was bought by social networking giant Facebook for one billion dollars in cash and stock.

Facebook, which is expected to launch a $5 billion initial public offering in May, will acquire Instagram’s entire team.
“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.”
