What was the name of McDonald’s advertising slogan introduced in 2003?

McDonald’s introduced the advertising slogan “I’m Lovin’ It” in 2003.

The campaign marked a major global branding effort for McDonald’s. Its short, conversational wording was designed to work across markets, and the phrase was paired with a distinctive musical identity. The campaign became one of the company’s longest-running international advertising platforms.

Justin Timberlake appeared in the original campaign’s music video, while the “ba da ba ba ba” musical hook became closely associated with McDonald’s commercials. The slogan is written in informal English, using “Lovin’” rather than the more formal “Loving.”

“I’m Lovin’ It” replaced earlier famous McDonald’s slogans in the company’s global advertising system, but older phrases continued to be remembered and reused in particular markets or retrospective campaigns.
