“January ad sales probably gained one percent,” said Jon Swallen, TNS’ senior vice president of research.

“The ad market has been stuck in the mud for 10 months. We're on this meandering track, and looking ahead, there's concern about the worsening economy," Swallen said in an interview, Bloomberg reported.
