“I'm Lovin' It” was introduced globally by McDonald's in 2003 as a worldwide advertising campaign.
The campaign was created to give McDonald's a more unified international voice after years of country-specific slogans. Its informal wording and upbeat tone were intended to connect the restaurant with enjoyment and everyday experiences rather than with a single menu item.
The campaign used music, television commercials, packaging, and other media. It became one of McDonald's longest-running modern brand platforms and remains strongly associated with the company.
The phrase is often written with the contraction and lowercase “Lovin'” exactly as McDonald's stylized it. It is also sometimes confused with earlier slogans such as “You Deserve a Break Today.”
