Which McDonald’s slogan was introduced in 2003 as part of a global campaign?

“I’m lovin’ it” was introduced by McDonald’s in 2003 as part of a global campaign.

The slogan used deliberately informal wording and the contraction “I’m,” giving it a conversational tone. It was paired with a sonic identity built around the phrase and became one of the company’s most widely used pieces of international branding.

The campaign followed several earlier McDonald’s slogans, including “You Deserve a Break Today.” Its broad wording was designed to work across markets and languages while connecting the restaurant with enjoyment and everyday experiences.

The slogan is sometimes written with different capitalization or punctuation in informal references, but the canonical English wording is “I’m lovin’ it.” It remains strongly associated with McDonald’s advertising worldwide.
