Which German advertising agency helped develop McDonald’s “I’m lovin’ it” campaign?

Heye & Partner helped develop McDonald’s “I’m lovin’ it” campaign.

The German agency was involved in creating the platform that McDonald’s launched worldwide in 2003. The campaign combined a simple spoken phrase, distinctive lowercase typography, and a musical identity designed to work across national markets.

McDonald’s advertising history includes several major agencies, which makes this fact easy to confuse. DDB Worldwide became strongly associated with McDonald’s advertising in the United States, while Leo Burnett also handled important McDonald’s work. Heye & Partner is specifically linked with the development of the “I’m lovin’ it” campaign.

The campaign’s international role was particularly important. Rather than presenting a completely different central slogan in every country, McDonald’s used one adaptable brand idea that could be translated and localized while retaining its recognizable core.
