The Young and the Restless [SEP] Introduction
The series is also syndicated internationally. "The Young and the Restless" originally focused on two core families: the wealthy Brooks family and the working class Foster family. After a series of recasts and departures in the early 1980s, all the original characters except Jill Foster were written out. Bell replaced them with new core families, the Abbotts and the Williamses. Over the years, other families such as the Newman family, the Barber/Winters family, and the Baldwin-Fishers were introduced. Despite these changes, one storyline that has endured through almost the show's entire run is the feud between Jill Abbott and Katherine Chancellor, the longest rivalry on any American soap opera.
