Lee Clow has decided to step down from his post as Chief Creative Officer at Apple’s advertising agency, TBWA/Media Arts Lab.

In his more than 40 years in advertising, he is best known for his work for Apple, which includes what many have called the best commercial of all time, “1984”, that launched the Macintosh computer; the now iconic dancing silhouettes for the iPod; and the more recent “Mac vs. PC” campaign featuring actors John Hodgman and Justin Long.
