Which 2003 McDonald's campaign featured the audio signature “ba da ba ba ba”?

McDonald’s “I’m Lovin’ It” campaign featured the audio signature “ba da ba ba ba.”

The short vocal hook was created to work alongside the tagline and make the campaign recognizable even when listeners could not immediately see a logo or product. Audio branding became especially valuable in television, radio, online video, and mobile media, where a brief sound can reinforce a visual identity.

The campaign launched internationally in 2003 and combined the English slogan with market-specific advertising. Justin Timberlake appeared in an early music video associated with the campaign, while the phrase and musical motif became the enduring corporate property associated with McDonald’s.

People sometimes remember the sound without knowing its campaign name, or confuse it with a separate commercial jingle. The defining pairing is the tagline “I’m Lovin’ It” and the “ba da ba ba ba” signature. Together they formed one of the most persistent elements of McDonald’s modern branding.
