A soap opera, soap, or soapie, is a serial drama on television or radio that examines the lives of many characters, usually focusing on emotional relationships to the point of melodrama. The term soap opera originated from such dramas being typically sponsored by soap manufacturers in the past.
The first serial considered to be a "soap opera" was Painted Dreams, which debuted on October 20, 1930 on Chicago radio station WGN. Early radio series such as Painted Dreams were broadcast in weekday daytime slots, usually five days a week, when most of the listeners would be housewives; thus, the shows were aimed at and consumed by a predominantly female audience. In the name, "soap" refers to the soap and detergent commercials originally broadcast during the shows, which were aimed at women who were cleaning their houses at the time of listening or viewing, and "opera" refers to the melodramatic character of the shows.
The first nationally broadcast radio soap opera was Clara, Lu, and Em, which aired on the NBC Blue Network at 10:30 p.m. Eastern Time on January 27, 1931.
One of the defining features that makes a television program a soap opera, according to Albert Moran, is "that form of television that works with a continuous open narrative. While Spanish language telenovelas are sometimes called "soap operas," telenovelas have conflicts that get resolved and a definite ending after (more or less) a year of daily weekday airing. But with soap operas each episode ends with a promise that the storyline is to be continued in another episode". In 2012, Los Angeles Times columnist Robert Lloyd wrote of daily dramas, "Although melodramatically eventful, soap operas such as this also have a luxury of space that makes them seem more naturalistic; indeed, the economics of the form demand long scenes, and conversations that a 22-episodes-per-season weekly series might dispense with in half a dozen lines of dialogue may be drawn out, as here, for pages. You spend more time even with the minor characters; the apparent villains grow less apparently villainous."
