CPB President Kathleen Cox hired a top FCC exec, Ken Ferree [his CPB bio], to fill her old job. The former Media Bureau chief will be c.o.o. Also appointed: David Creekmore, new v.p. finance and administration, replacing Betsy Griffith, and Nancy Rohrbach [bio] in the frequently vacant position of senior v.p., corporate and public affairs. Ferree is a lawyer and tall guy (FCC photos) who has pushed and pulled for the DTV transition. A Washington Post feature earlier cited him as an example of federal aides who move on when their bosses do. Chairman Michael Powell, who knew Ferree in law school and hired him, leaves the FCC this week. Creekmore has been senior director of business planning.
