The loss of trust of large advertisers to YouTube is due to the fact that control over thematic matching did not exclude the possibility of an error in fixing ad units to the uploaded video on Youtube.

This error led to the fact that the commercials of some large advertisers was broadcast at the beginning of the videos of an anti-Semitic or racist content. This presence did not suit many large advertisers and they stopped cooperation with YouTube which caused serious losses for Google.

The international communication holding company Omnicom will help to restore the trust of advertisers to YouTube. According to AdIndex, Omnicom is ready to provide its customers (including such giants as AT & T, Pepsi, Procter & Gamble and Volkswagen) the mechanism allowing to supervise conformity of their advertising blocks on YouTube with high accuracy.
