Ad company Omnicom's revenue dips 1.5 pct

Feb 15 (Reuters) - U.S. advertising company Omnicom Group Inc's revenue dipped 1.5 percent in the fourth quarter, as many domestic clients curbed marketing budgets and due to stiffer competition from consulting firms.

Revenue fell to $4.18 billion in the quarter ended Dec. 31, from $4.24 billion a year earlier, Omnicom said on Thursday. (Reporting by Sonam Rai in Bengaluru; Editing by Savio D'Souza)
