“I’m Lovin’ It” debuted in 2003 and became McDonald’s global advertising tagline.
The campaign was launched internationally in 2003 as McDonald’s sought a more unified worldwide brand message. The phrase used conversational language and the contraction “I’m,” giving it a casual tone intended to sound natural in advertising and popular culture.
The campaign is closely associated with a jingle and with the performer Justin Timberlake, who appeared in promotional material connected with its launch. The slogan was adapted across markets and languages, but the English phrase became the best-known version of the campaign.
It followed several earlier McDonald’s slogans, including “You Deserve a Break Today,” which was introduced in the 1970s. “Have It Your Way” belongs to Burger King, so it is a frequent wrong answer in fast-food slogan quizzes. “I’m Lovin’ It” remains one of McDonald’s most recognizable modern branding lines.
