AdAge reports today on The Dallas Morning News outsourcing its national ad sales to Tribune division Tribune 365. This could be a trend and it makes some sense. However, it doesn't appear that the Dallas Morning News expects this outsourcing to yield more national advertising revenue, as much as it will reduce costs.

CHICAGO (AdAge.com) -- In what's believed to be a first-of-its-kind arrangement in the struggling newspaper industry, Belo's Dallas Morning News has tapped rival publisher Tribune Co. to handle its national ad sales.

The move figures to let the Morning News dedicate its sales resources to the local market without completely turning its back on national ad sales, while Tribune's national-sales unit, called Tribune 365, gets to sweeten an offering that already includes the Chicago Tribune, Los Angeles Times, Baltimore Sun, Ft. Lauderdale Sun-Sentinel and other papers, and pocket a few sales commissions in the process.
