Specializing in technology marketing, Segall was Steve Jobs' agency creative director for 12 years spanning NeXT and Apple, and also served as worldwide creative director at agencies for Dell, Intel and IBM.
His father's position with a retail chain forced the family to move several times before he was 10, taking him to Salina, Kansas, Ashtabula, Ohio, Detroit once again, and finally to Livingston, New Jersey.
He graduated from Livingston High School in 1968 and earned a Bachelor of Science degree at Pennsylvania State University in 1972.
There, Segall was global creative director for the "Think different" campaign, co-writer of the "Crazy Ones" launch commercial,[2] and originated the "i" strategy behind the naming of iMac,[3][4][5] iPod, iPhone and iPad.
In later years, Segall served as creative director for Intel at agency Euro RSCG,[6] and chief creative officer at Enfatico (previously DaVinci),[7] a worldwide network of 13 offices handling marketing for computer-maker Dell.
