The decline of auto ads in newspaper-classifieds may be turning into a full-fledged landslide, the Wall Street Journal reports (via MediaBuyerPlanner). The Tribune Co. said last week that auto-classified revenue at its newspapers sank 16 percent in December, Lee Enterprises Inc. reported a 15.2 percent drop in the same category for the fourth quarter, and McClatchy Co. said its papers saw a 20 percent decline for December. McClatchy chief executive and chairman Gary Pruitt said that the company's California papers had held up well in automotive advertising, but that the industry wide decline finally reached the West Coast in the fourth quarter.
