In this new role, Jouning will have responsibility for the entire commercial side of Condé Nast's digital business in the UK. The appointment will take effect from 1 January 2010.
Prior to launching Wired in March 2009, Jouning was associate publisher of GQ and GQ Style. He has also been promotions director of GQ and sponsorship manager for Sky TV.
Nicholas Coleridge, managing director of Condé Nast, said: "Jamie's appointment is a measure of the importance we are attaching to Digital, and his considerable publishing experience and contacts in the agency and client worlds will be of great benefit to the project.
"During his time as launch publisher of Wired, his leadership of the team, energy and strategic intelligence has helped the magazine establish itself very rapidly in the marketplace, and I know he will make a similar impact in Digital."
Condé Nast Digital Britain has thirteen websites and is the UK division of Condé Nast Digital International.
The new publisher of Wired magazine is yet to be announced.
