Huffington Post still not turning a profit

Reuters reports that the center-left Huffington Post has yet to turn a profit, despite a massive investment from AOL Inc. in 2011:

With AOL's backing - it has injected tens of millions of dollars into the website - The Huffington Post has been able to do much more than give out cardigans [to its employees] every year. Its audience has more than tripled from 25 million people before the AOL deal to 84 million at the end of October, according to comScore data. It has branched out to cover lifestyle, entertainment, business and technology, mushrooming to 60 vertical sites from about 20.

But The Huffington Post has yet to turn a profit for AOL, falling far short of Armstrong's projection at the time of the acquisition that the unit would post $66 million in operating profit in 2013 on $165 million in revenue.
