The show is set in a fictional Wisconsin town called Genoa City, which is unlike and unrelated to the real life village of the same name, Genoa City, Wisconsin. First broadcast on March 26, 1973, The Young and the Restless was originally broadcast as half-hour episodes, five times a week. The show expanded to one hour episodes on February 4, 1980. In 2006, the series began airing encore episodes weeknights on SOAPnet until 2013, when Y&R moved to TVGN (now Pop).
