The CNN presents an interview with Maurice Levy, president of Publicis, the world's fourth largest advertising company. Talking to Todd Benjamin, Mr Levy shares his ideas on leadership, personality and atmosphere and when asked whether Publicis wants to be the world's biggest advertising company he replies:

"The most important ambition in the world is not to be the biggest. You don't need just a big checkbook to be the best. To have the best people, to attract the best client, to sell them the best work; this is a real ambition. This is a much bigger ambition than just a question of numbers."
