Which slogan did McDonald’s launch in 2003 as its global brand message?

McDonald’s launched “I’m Lovin’ It” in 2003 as its global brand message.

The campaign began internationally in September 2003 and was designed to give McDonald’s a more unified voice across markets. Its short, conversational wording emphasized enjoyment and everyday experiences rather than describing a specific menu item. The slogan was paired with a distinctive five-note musical signature that became central to the campaign.

The branding effort followed several years in which McDonald’s used different advertising approaches and slogans in different countries. “I’m Lovin’ It” gave the company a phrase that could be translated or adapted while preserving a common global identity. The campaign also used music and youth-oriented imagery to connect the restaurant with popular culture.

The slogan is sometimes associated only with the advertising jingle or with Justin Timberlake’s recorded contribution. The phrase itself is McDonald’s corporate advertising message, while Timberlake’s involvement concerned the campaign’s musical material. Earlier slogans, including “You Deserve a Break Today,” belonged to separate campaigns.
