Omnicom's total revenues rose by 7.9 per cent to $2.8 billion. However, ad revenues showed the slowest growth among Omnicom's four disciplines, rising 5.7 per cent to $1.2 billion, while customer relationship marketing revenues increased by 9.6 per cent to £978.6 million, PR revenues by 8.9 per cent and speciality revenues by 10.8 per cent.
Omnicom, led by its chief executive, John Wren, said that the increases were driven by new business and a "modest growth" in client spend.
The company has also made a series of acquisitions in the second quarter of the year. Among these were two US-based content companies - EVB and EMP.
