Huffington Post
Revenues: They’re not available, but the web giant once aimed to triple sales from $30 million in 2010 to $100 million last year. It was briefly profitable in 2010, but not since it was sold to AOL in early 2011.
Gawker Media
Founder Nick Denton has said he’s looking to grow revenue 40% this year and thinks sales will be a $100-plus million business “someday.” Profitable? Yes, possibly since 2006.

Revenues quadrupled through most of 2012. Profitable? Information not available.
