What global McDonald’s campaign slogan debuted in 2003?

McDonald’s global campaign slogan that debuted in 2003 was “I’m Lovin’ It.”

The campaign launched internationally in 2003 and used the distinctive “ba da ba ba ba” musical signature with the slogan. It was designed as a unified global branding platform rather than a short-lived slogan for only one country.

The campaign is often associated with Justin Timberlake because he appeared in related promotional material and recorded a song connected with it. However, the slogan itself is McDonald’s brand line, not the title of a Timberlake album or a restaurant product.

“I’m Lovin’ It” followed earlier McDonald’s slogans such as “You Deserve a Break Today.”
