What four-word slogan did McDonald’s launch globally in 2003?

McDonald’s launched the global slogan “I’m Lovin’ It” in 2003.

The campaign was introduced internationally as a unified brand platform, replacing a series of locally varying advertising messages. Its short, conversational wording was designed to sound like an expression of personal enjoyment rather than a formal corporate claim.

The campaign was associated with a jingle and with recording artist Justin Timberlake, who appeared in promotional material connected with its launch. The phrase was adapted across languages and markets while retaining the same English title in many brand references.

“I’m Lovin’ It” followed earlier McDonald’s slogans such as “You Deserve a Break Today.” It remains one of the company’s longest-running global advertising platforms, although individual markets have also used additional local campaigns.
