What advertising slogan did McDonald's launch internationally in 2003?

McDonald's launched the international advertising slogan “I'm lovin' it” in 2003.

The campaign marked a major shift toward a shorter, music-led global identity. McDonald's introduced the English-language slogan in markets around the world while adapting the surrounding advertisements for local audiences. The phrase was paired with a distinctive five-note musical motif that became central to the campaign's branding.

The slogan replaced earlier McDonald's campaigns such as “You Deserve a Break Today,” which had been used since 1971. It was designed to express an upbeat emotional reaction to the brand rather than describe a specific product or promotion.

Some accounts focus on the song associated with the campaign, while others focus on the slogan itself. The question asks for the slogan, whose official styling includes a lowercase “lovin'” and an apostrophe.
