<P> Because it was scheduled to lead off Fox's Sunday - night animated programming lineup, portions of King of the Hill episodes were often pre-empted by sporting events that ran into overtime; in season nine especially, whole episodes were pre-empted . Ultimately, enough episodes were pre-empted that the majority of the series' 10th season--initially intended to be the final season, consisted of unaired ninth - season episodes . </P> <P> The 13th - season episode "Lucky See, Monkey Do" became the first episode of the series to be produced in widescreen high definition when it aired on February 8, 2009 . </P> <P> Although ratings remained consistent through the 10th through 12th seasons and had begun to rise in the overall Nielsen ratings (up to the 105th most watched series on television, from 118 in season 8), Fox abruptly announced in 2008 that King of the Hill had been cancelled . The cancellation coincided with the announcement that Seth MacFarlane, creator of Family Guy and American Dad!, would be creating a Family Guy spin - off called The Cleveland Show, which would take over King of the Hill's time slot . </P> <P> Hopes to keep the show afloat surfaced as sources indicated that ABC (which was already airing Judge's new animated comedy, The Goode Family) was interested in securing the rights to the show, but in January 2009, ABC president Steve McPherson said he had "no plans to pick up the animated comedy ." </P>
