PaidContent.org reports that Huffington Post has hired Focus Media to go after the rebounding Detroit automakers for potential advertising deals.

In a statement, Huffington Post chief revenue officer Greg Coleman said: “Given the size and importance of the big three domestic carmakers, hiring a designated rep to work with them is a milestone for HuffPost in our continued national sales expansion,” according to PaidContent.

It adds that: “In terms of charting the spending rebound among car makers, last fall, local media forecaster Borrell Associates predicted that total U.S. ad spend for new cars would rise to $19.2 billion this year from the low of $18.4 billion in 2009. As a small sign of a revival in ad spend, GM, long considered a bellwether when it comes to the direction of ad dollars, inched up its spending 1.3 percent last year, according to recent figures from Kantar Media."

Time to cash in.
