Even though Dallas and Knots Landing (by the skin of it's teeth) both premiered in the 70's, they're generally regarded as "80's soaps" as the bulk of their lifespan was within that decade. The 60's had Peyton Place, the 80's had the Big Four, the 90's had Melrose Place and 90210, the 00's had Desperate Housewives and this decade has Empire. Why didn't the 70's have a successful primetime soap to call it's own? From what I've read, there was only a few attempts to launch a primetime soap during the early and mid-70's. Harold Robbins' The Survivors was first out the gate in the fall of 1969 but it was cancelled in early 1970. After that, the only two I've read about were Beacon Hill, an American take on Upstairs Downstairs in 1975 and Executive Suite in 1976. Were there more that launched but sank without trace? Was there not a thirst to replicate the success of Peyton Place from the decade prior or had a snobbery returned to TV that regarded soaps to be daytime fare?
