What phrase became McDonald's first global brand campaign in 2003?

“I'm Lovin' It” became McDonald's first global brand campaign in 2003.

The campaign was created to give McDonald’s a single platform that could be used across countries and languages. Its short phrase, upbeat tone, and distinctive “ba da ba ba ba” mnemonic were designed to work in television commercials, radio, packaging, and other communications.

The campaign represented a shift from many separate national slogans toward a more unified international identity. McDonald’s still adapted advertising details for local markets, but the central phrase and musical signature gave the brand a common worldwide language.

A frequent mix-up concerns the song and the campaign. The phrase was used for McDonald’s branding, while the launch materials also involved music associated with Justin Timberlake. The branding answer is the phrase itself, not the performer or a particular commercial.
