LOS ANGELES (AP)  King of the Hill is over the hill at Fox, which is canceling the long-running animated comedy. Final episodes of the half-hour series, now in its 13th year, likely will air during the 2009-10 season, Fox said Friday. The network recently ordered 13 new episodes, and animated series have a long production schedule. King of the Hill chronicles the life of blue-collar family man Hank Hill of Texas and his family and friends. Hank is voiced by series co-creator and executive producer Mike Judge. Others in the cast include Kathy Najimy, Brittany Murphy and Stephen Root. The picture is brighter for another Sunday night animated show on Fox, American Dad, which was renewed for its fifth season. It has posted single-digit ratings gains among advertiser-favored young adult viewers and total viewers. Ratings for King of the Hill have been relatively flat early this season. American Dad is about Stan Smith, a dedicated conservative, and his oddball family in Langley, Va. Series co-creator and executive producer Seth MacFarlane voices Stan in the series, which also features the voices of Wendy Schaal, Rachael MacFarlane and Scott Grimes.
