Which fast-food company introduced the slogan “I’m Lovin’ It” in 2003?

McDonald’s introduced the slogan “I’m Lovin’ It” in 2003. It became the company’s first global advertising campaign and was designed to give McDonald’s a consistent worldwide brand message.

The campaign began in Munich, Germany, and was adapted across many countries and languages. Its best-known musical element was a jingle performed in English by Justin Timberlake, with production connected to the advertising campaign and later commercial releases.

The slogan is sometimes confused with older McDonald’s lines such as “You Deserve a Break Today” and “You’re the One.” “I’m Lovin’ It” was distinctive for its conversational style and use of the apostrophe in “Lovin’.”

The campaign helped unify McDonald’s international marketing while allowing local advertisements to feature regional celebrities, foods, and cultural references. The phrase remains one of the most durable slogans in fast-food advertising.
