In 2004, ABC's average viewership declined by ten ratings points, landing the network in fourth place, behind NBC, CBS and Fox (by the following year, the combined season-ending average audience share of ABC, NBC and CBS represented only 32% of U.S. households). However, during the 2004–05 season, the network experienced unexpected success with new series such as Desperate Housewives, Lost and Grey's Anatomy as well as reality series Dancing with the Stars, which helped ABC rise to second place, jumping ahead of CBS, but behind a surging Fox. On April 21, 2004, Disney announced a restructuring of its Disney Media Networks division with Anne Sweeney being named president of ABC parent Disney–ABC Television Group, and ESPN president George Bodenheimer becoming co-CEO of the division with Sweeney, as well as president of ABC Sports. On December 7, 2005, ABC Sports and ESPN signed an eight-year broadcast rights agreement with NASCAR, allowing ABC and ESPN to broadcast 17 Nextel Cup races each season (comprising just over half of the 36 races held annually) effective with the 2006 season.
