What phrase appears in McDonald's global slogan introduced in 2003?

“I'm Lovin' It” is the phrase in McDonald's global slogan introduced in 2003.

McDonald's launched the campaign internationally in 2003, using the phrase with a distinctive five-note musical motif. It was designed as a flexible global platform that could be adapted to different countries while keeping a consistent brand message.

The campaign marked a shift toward contemporary music, youth culture, and emotional language. Justin Timberlake appeared in an early campaign advertisement, and the musical hook became closely linked to McDonald's identity.

The phrase is often confused with older American slogans such as “You Deserve a Break Today.” Those slogans belonged to earlier campaigns; “I'm Lovin' It” became the company's principal worldwide platform in the 2000s.
