Fox mainly stayed away from daytime soaps, and has not attempted them since their ascension to major-network status in 1994 (it did later attempt a series of daily prime time soaps, which aired on newly created sister network MyNetworkTV, but the experiment was largely a failure). Due to the masses of episodes produced for a series, release of soap operas to DVD (a popular venue for distribution of current and vintage television series) is considered impractical. With the exception of occasional specials, daytime soap operas are notable by their absence from DVD release schedules (an exception being the supernatural soap opera, Dark Shadows, which did receive an essentially complete release on both VHS and DVD; the single lost episode #1219 is reconstructed by means of an off-the-air audio recording, still images, and recap material from adjacent episodes). Performers See List of longest-serving soap opera actors Soap opera performers in the United States are typically divided into two main groups: primary characters (sometimes referred to as "contract players" – as their portrayers signed contracts of employment – or leading characters) and secondary characters (sometimes referred to as recurring characters). These two groups of characters make up the vast majority of the people who appear on any given soap. There are also characters who appear only for a short time as dictated by a specific storyline, and even characters who may only get a first name and no fleshed-out character history with little dialogue (these are sometimes referred to as "under-5s" since they receive under five lines of dialogue in each episode). Due to the longevity of these shows, it is not uncommon for a single character to be played by multiple actors. The key character of Mike Karr on The Edge of Night was played by three actors. Conversely, several actors have remained playing the same character for many years, or decades even. Helen Wagner played Hughes family matriarch Nancy Hughes on American soap As the World Turns from its April 2, 1956, debut through her death in May 2010. She is listed in the Guinness Book of World Records as the actor with the longest uninterrupted performance in a single role. A number of performers played roles for 20 years or longer, occasionally on more than one show. Rachel Ames played Audrey Hardy on both General Hospital and Port Charles from 1964 until 2007, and returned in 2009. Susan Lucci
