The Business Insider is now profitable—just barely. In a post this morning reporting the digital media startup's revenues, operating profits, and other metrics, Henry Blodget reveals that his collection of bloggy news sites and budding conferences eked out a net profit of $2,127, on revenues of $4.8 million last year. It's about enough, Blodget notes, for a MacBook Pro. But that's actually quite an achievement for a media startup. Remember, the Business Insider was founded only in 2007, and this achieved profitability in its third year of operations. And as you can see by the chart above, its really the revenues that you want to keep an eye on. To put that $4.8 million in perspective, that's roughly half of TechCrunch's 2010 revenues of $10 million. Not bad.
