Lucy Hood exits News Corp.

Jamba chief will be replaced by Lee Fenton

News Corp. exec Lucy Hood, who has led the conglom’s efforts in mobile entertainment for the past several years, unexpectedly ankled Wednesday.

For the past year, she has headed up Jamba, a European company with which Fox merged much of its mobile content operation. Prior to that, Hood was the head of Fox Mobile Entertainment since 2005. She has held various other positions at News Corp. for more than a decade.

In a statement, Hood said she wants to pursue “more entrepreneurial ventures.”

Fox has had success with mobile-phone voting for “American Idol,” but its other initiatives, such as “mobisodes” based on “24” and “The Simple Life,” haven’t gained much traction, particularly in the U.S. Like most of its competitors, Fox has found that Americans aren’t yet very interested in video content on their cell phones.

Replacing Hood will be Lee Fenton, Jamba’s chief operating officer. He joined the venture from European cell-phone company Vodafone last year.
