Turns after the series ended. The structure of Peyton Place, with its episodic plots and long-running story arcs, set the mold for the prime time serials of the 1980s, when the format reached its pinnacle. The successful prime time serials of the 1980s included Dallas, its spin-off Knots Landing, Dynasty, and Falcon Crest. These shows frequently dealt with wealthy families, and their personal and big-business travails. Common characteristics were sumptuous sets and costumes, complex storylines examining business schemes and intrigue, and spectacular disaster cliffhanger situations. Each of these series featured a wealthy, domineering, promiscuous, and passionate antagonist as a key character in the storyline – respectively, J.R. Ewing (Larry Hagman), Abby Cunningham (Donna Mills), Alexis Colby (Joan Collins), and Angela Channing (Jane Wyman). These villainous schemers became immensely popular figures that audiences "loved to hate". Unlike daytime serials, which are shot on video in a studio using the multi-camera setup, these evening series were shot on film using a single camera setup, and featured substantial location-shot footage, often in picturesque locales. Dallas, its spin-off Knots Landing, and Falcon Crest all initially featured episodes with self-contained stories and specific guest stars who appeared in just that episode. Each story was completely resolved by the end of the episode, and there were no end-of-episode cliffhangers. After the first couple of seasons, all three shows changed their story format to that of a pure soap opera, with interwoven ongoing narratives that ran over several episodes. Dynasty featured this format throughout its run. The soap opera's distinctive open plot structure and complex continuity was increasingly incorporated into American prime time television programs of the period. The first significant drama series to do this was Hill Street Blues. This series, produced by Steven Bochco, featured many elements borrowed from soap operas, such as an ensemble cast, multi-episode storylines, and extensive character development over the course of the series. It and the later Cagney & Lacey overlaid the police series formula with ongoing narratives exploring the personal lives and interpersonal relationships of the regular characters. The success of these series prompted other drama series, such as St. Elsewhere and situation comedy series, to incorporate serialized stories and story structure to varying degrees. The prime time soap operas and drama series of the 1990s, such as Beverly Hills, 90210, Melrose Place, Party of Five, The OC, and Dawson's Creek, focused more on younger characters. In the 2000s,
