What global tagline did McDonald’s launch in 2003?

McDonald’s launched the global tagline “I’m Lovin’ It” in 2003.

The campaign marked a move toward a more unified international brand voice. The phrase was used in advertising, packaging, music, and other communications, allowing McDonald’s to connect markets through one short, conversational expression. Its informal wording was designed to sound like a customer’s reaction rather than a formal corporate claim.

The tagline is often associated with the “ba da ba ba ba” musical signature used in the campaign, although the slogan and the audio mnemonic are separate elements of the branding. “I’m Lovin’ It” also replaced the earlier era’s most famous lines in McDonald’s worldwide communications.

McDonald’s has adapted advertising executions for different countries, but the English tagline became a central part of its global identity. The apostrophe and first-person wording are part of the official form, making it distinct from generic phrases such as “We love it.”
