Major ad firms mulling job cuts: report

(Reuters) - Advertising firms Interpublic Group, Omnicom Group Inc and WPP Group are weighing further job cuts as the advertising market deteriorates, the New York Post reported.

Agencies run by WPP, the world's second-largest advertising company, are bracing for cuts across the board in January, the paper said, citing sources.

Interpublic is mulling layoffs in the event General Motors Corp slashes its ad spending even further or reduces its stable of car brands, the paper said.

Most of GM's U.S. advertising is handled by units of Interpublic and Publicis Groupe SA.

Several agencies run by Omnicom, the world's largest ad company, have seen job cuts this year, and those agencies are expected to make additional cuts next year, the paper said, citing industry watchers.

Interpublic, Omnicom and WPP could not be immediately reached for comment.
