What McDonald’s slogan was introduced internationally in 2003?

“I’m Lovin’ It” was introduced internationally as a McDonald’s slogan in 2003.

The phrase became the centerpiece of a global campaign designed to give McDonald’s a more consistent worldwide voice. It was used in advertising, packaging, restaurant materials, and other brand communications across many markets.

The campaign also introduced the short vocal melody commonly associated with the slogan. The English phrase was retained in numerous countries, although local advertising could be adapted to different languages and cultural settings.

“I’m Lovin’ It” is sometimes mistakenly dated to the 1990s because McDonald’s had several prominent campaigns during that decade. It is also distinct from “You Deserve a Break Today,” the major slogan associated with the early 1970s. The 2003 campaign remains one of the clearest examples of McDonald’s global brand standardization.
