Tuesday, January 22 at 8:00 p.m.

“Dallas” and “Dynasty” kicked off the nighttime soap frenzy in the late 1970s and spun off the long-lasting series “Knots Landing.” Sometimes forgotten is the genre’s antecedent: 1964’s “Peyton Place,” which starred Mia Farrow and Ryan O’Neal.

Interviewees in this episode include Larry Hagman, Joan Collins, Linda Evans, Diahann Carroll, Linda Gray, Patrick Duffy, Michele Lee (at right), Joan Van Ark (at left) and Donna Mills.
