In 1936, as television networks CBS, DuMont, and NBC experimented with new ways to provide entertainment, NBC deviated from the traditional method of single experimental programs to broadcast the first multi-part program, Love Nest, over a three-episode arc. This would come to be known as a miniseries. Although the term was not coined until 1954, several other such miniseries were broadcast, including Jack and the Beanstalk and Women in Wartime.
In the mid-1960s the concept was developed into a genre that still exists. While the major broadcast networks pioneered the idea, it quickly became popular with cable and streaming services.
