What was the name of McDonald’s global advertising campaign launched in 2003?

McDonald’s launched its global advertising campaign “I’m Lovin’ It” in 2003.

The campaign marked a move toward a more unified worldwide brand message. Its short, conversational phrase was designed to work across markets, while local advertising could still adapt the details to regional audiences. The campaign became closely associated with a distinctive five-note musical signature.

The song connected with the campaign was recorded by Justin Timberlake, and the phrase itself became a long-running part of McDonald’s branding. It is separate from earlier slogans such as “You Deserve a Break Today.” Because McDonald’s has used many locally adapted campaigns, the 2003 launch date specifically identifies the global “I’m Lovin’ It” platform.
