What slogan did McDonald’s launch worldwide in 2003?

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

The campaign was introduced as a global marketing platform and used the phrase across television, print, packaging, music, and restaurant materials. Its deliberately informal wording was designed to sound conversational and connect food with an upbeat emotional response.

The slogan replaced neither the company name nor the Golden Arches; it worked alongside those established identity elements. It also followed earlier McDonald’s advertising lines, including “You Deserve a Break Today,” which became prominent in the 1970s.

“I’m Lovin’ It” remains especially notable because McDonald’s retained it across many markets and languages, making it one of the company’s longest-running modern slogans. The apostrophe and lowercase “lovin’” are part of the campaign’s familiar written form.
