Which McDonald's slogan launched globally in 2003?

“I'm Lovin' It” was the McDonald's slogan launched globally in 2003.

The campaign introduced a short, conversational phrase designed to work across languages and markets. Its wording focused on a personal reaction to the McDonald's experience rather than describing a specific product. The slogan was paired with the now-famous “ba da ba ba ba” musical signature, which became a major part of the campaign's identity.

McDonald's developed the campaign with the German agency Heye & Partner and rolled it out internationally beginning in 2003. The launch represented a move toward a more unified global brand platform, while local advertising still adapted the message for different countries.

The slogan is sometimes confused with “You Deserve a Break Today,” the major McDonald's campaign from 1971, or with “We Love to See You Smile,” used in the 1990s. Those slogans belong to earlier periods. “I'm Lovin' It” is the one associated with the global campaign that began in 2003.
