FCC Chairman Kevin Martin on Wednesday took issue with comments from an official of the Government Accountability Office that "there is no one in charge" of the national conversion to all-digital television, which must be fully implemented by February 18, 2009. "There seems to be confusion even on the part of the FCC, between the chairman and some other commissioners, regarding what its responsibilities are for the transition," Mark Goldstein, the GAO's director of physical infrastructure, had said in Senate testimony. But FCC spokeswoman Mary Diamond quoted Martin as responding, "There is no confusion at the [FCC]. We are committed to putting polices in place to ensure a smooth transition."
