PBS has restructured its senior management, effective immediately, elevating programmer/producer Beth Hoppe to chief programming executive and general manager, according to a memo circulated to PBS stations today. Chief programmer John Wilson, who has worn many hats since joining PBS in 1994, will focus on fundraising programs as senior v.p., pledge strategy and special projects. Wilson will “build on the experiments undertaken this year to reshape our pledge programming and will continue to work closely with PBS colleagues, producers and stations to develop these plans,” said PBS Chief Operating Officer Michael Jones, in his memo announcing the management changes. Hoppe signed on at PBS last year as one of Wilson’s deputies. She has specialized in nonfiction programming during a TV career that includes a run as one of PBS’s hottest producers and a stint producing and developing science programming for Discovery Studios.
