What was McDonald’s worldwide advertising slogan launched in 2003?

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

The slogan became the central phrase of a major global branding platform and was paired with the familiar “ba da ba ba ba” musical signature. McDonald’s used the campaign across many countries, adapting advertisements to local languages and cultures while keeping the English-originated brand line recognizable.

The campaign represented a shift toward expressing enjoyment and personal experience. Earlier slogans often highlighted service, convenience, or taking a break; “I’m Lovin’ It” focused on the customer’s positive emotional reaction.

The slogan is still commonly associated with McDonald’s, although local advertising can include additional wording and market-specific campaigns. It should not be confused with the chain’s earlier 1971 slogan, “You Deserve a Break Today.”
