What global McDonald’s campaign launched in 2003?

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

The campaign introduced a short, conversational phrase intended to work across languages and markets. Its wording was paired with the “ba da ba ba ba” musical signature, which became strongly associated with McDonald’s advertising. The campaign represented a major effort to give the multinational company a consistent global identity.

The launch was connected with creative work developed in Germany, and Justin Timberlake appeared in an early promotional music video associated with the campaign. The phrase itself became more important than any single commercial or performer and continued to be used internationally.

A common mistake is to identify “You Deserve a Break Today” as the modern slogan because it is also one of McDonald’s most famous lines. That slogan belongs to 1971. “I’m Lovin’ It” is the later campaign that began in 2003 and remains one of the brand’s signature phrases.
