According to Turley, he is departing to take a role at MTV:
So why am I leaving? Well, after writing all this, I’m wondering the same thing.. but it’s time for me to learn something new and work with different content for a different audience. MTV has always created culture and ideas that define generations. The opportunity to work with animators, video artists, journalists, designers, musicians, artists – creating content, creating culture, for an audience as big as MTV’s is really exciting.
Turley had been Businessweek’s creative director for the past four years. Before joining the magazine, he worked for The Guardian.
