One of the most influential decades in television was the 1970s. The world was changing at a rapid pace, and it only made sense that the shows on TV would reflect the same cultural shift. The wholesomeness of 60s hits likeThe Andy Griffith Showgave way to more grounded comedic offerings likeAll in the Family.

These programming changes would not only usher in creative geniuses likeNorman Learbut also shape the future of television for years to come.The following 1970s shows influenced the next wave of television shows and the viewers who watched them.

Created by David Jacobs

One of the most famous and influential families on television is easily the Ewing clan, who were the stars of the primetime soap,Dallas. The series followed the complicated lives of the Ewing family as weekly dramas stemmed from infighting about the family’s oil business, usually between the upstanding Bobby (Patrick Duffy) and his devious brother J.R. (Larry Hagman).

Thetwists and turns ofDallasproved that serialized storytelling would not scare off viewerswho would schedule their evenings around their favorite show.Dallas, or rather, J.R., proved that the main character of a series didn’t have to be of strong moral fiber or learn a valuable lesson by episode’s end. The overwhelming popularity of the character people loved to hate would open the door for future antiheroes to grace the screen to make lives miserable for the entertainment of others.

Created by Ivan Goff and Ben Roberts

Three strong and skilled women are recruited to put their abilities to use for a private investigation agency in the hit action series,Charlie’s Angels.

7’MAS*H' (1972–1983)

Created by Larry Gelbart

War was hell, but the doctors and nurses ofMASHrefused to have their spirits broken. Based on the 1970 film of the same name,MASHfollowed the struggles of the medical staff who worked in the high-pressure surgical tents in Korea during the Korean War. The series boasted an impressive ensemble cast, but episodes predominantly followed Chief Surgeon “Hawkeye” Pierce (Alan Alda) as he did everything possible to amuse himself as a distraction from the horrors surrounding him.

MASHdidn’t become one ofthe most popular comediesof the era without breaking some rules.MASHbroke new ground in comedy by being unafraid to explore serious issues to create stories that could be as emotional as they were humorous. Equally important to the future of sitcoms was the use of a single-camera technique that removed the established look of actors on a stage that audiences had grown accustomed to.

Detective shows had a certain type of tone they stuck to beforeThe Rockford Files. There seemed to be conventional wisdom that the mysteries needed to be serious for them to be entertaining, and the detectives were required to be tough and stoic to draw viewers.The Rockford Filesignored thisto make a detective who was humorous and intelligent in a way that felt more relatablethan the hard-nosed trope of a loner tough guy.

1’All in the Family' (1971–1979)

​​​​​​​​​​​​​​Equal parts funny and controversial,All in the Familywas the most influential show of the 1970s. The sitcom followed the lives of the Bunker family, with patriarch Archie (Carol O’Connor) ranting his way through each episode at anyone who would listen. Although his wife Edith (Jean Stapleton) was happy to listen, adult daughter Gloria (Sally Struthers) and her husband Michael (Rob Reiner) would challenge his conservative opinions with their liberal views.

All in the Familychallenged the idea of traditional entertainment by injecting realism into its comedy. The concept of a conventional sitcom starring a cheery family was thrown out the window in favor of arguments about politics that mirrored the hostility of real households during a time of rising generational conflict. Archie’s rudeness and resistance to new ideas worked for both sides of the political audience, who each found a different reason to find the main character entertaining.
