What global McDonald’s slogan launched in 2003?

McDonald’s launched the global slogan “I’m Lovin’ It” in 2003.

The campaign marked a major branding shift because McDonald’s used one central slogan across international markets. Its casual wording and pop-oriented presentation were intended to connect the brand with contemporary music, enjoyment, and everyday experiences.

The campaign is closely associated with a jingle performed by Justin Timberlake. The song and slogan helped give McDonald’s a consistent international identity while allowing local advertising to vary in language and execution.

A frequent mistake is to treat “I’m Lovin’ It” as merely a song title or a temporary advertisement. It became a long-running McDonald’s brand platform, succeeding earlier slogans such as “You Deserve a Break Today.”
