McDonald’s launched the advertising slogan “I’m lovin’ it” in 2003 as a global brand campaign.
The campaign introduced a more contemporary, conversational tone for McDonald’s advertising. Its signature musical hook was performed in the campaign’s best-known version by Justin Timberlake, while the slogan appeared in advertisements and restaurant marketing around the world.
“I’m lovin’ it” was notable because McDonald’s used the same central line internationally, adapting surrounding executions for different languages and markets. That approach helped connect local advertising to a unified global identity.
People sometimes confuse the slogan with earlier McDonald’s lines such as “You Deserve a Break Today,” which dates from the early 1970s. “I’m lovin’ it” is the later campaign that became closely associated with the modern McDonald’s brand.
