Which McDonald's slogan, introduced globally in 2003, used the phrase “lovin’”?

“I’m Lovin’ It” was the McDonald's slogan introduced globally in 2003.

The campaign marked a major effort to give McDonald's a single, contemporary identity across international markets. Its short, conversational wording was designed to work across languages and advertising formats while connecting food with an upbeat emotional response.

The phrase became one of McDonald's longest-running global brand messages. Its campaign included television commercials, packaging, in-store materials, and a musical theme that helped make the wording instantly recognizable.

The slogan is often associated with the singer Justin Timberlake because he recorded the best-known vocal version used in the campaign. The singer, however, is a different fact from the slogan itself.
