Diefenbach will be CPB TV production grantmaker

Greg Diefenbach, a longtime executive producer at a major supplier of PBS programs, Devillier Donegan Enterprises, is CPB's new senior v.p. for TV programming. At DDE he oversaw the PBS world history series Empires ("great eras of struggle ... explosive creativity, ultimate depravity...") among 100 hours of programming. He succeeds Michael Pack, who returned to documentary production. Pack colleague John Prizer remains at CPB as an advisor to President Pat Harrison.
