<P> In 1970, ABC debuted Monday Night Football as part of its Monday prime time schedule; the program became a hit for the network and served as the National Football League (NFL)'s premier game of the week until 2006, when Sunday Night Football, which moved to NBC that year as part of a broadcast deal that in turn saw MNF move to ESPN, took over as the league's marquee game . According to Goldenson, Monday Night Football helped earn ABC regularly score an audience share of 15%--16%; ABC Sports managed the budget for the Monday night time slot to reallocate the weekly budget for ABC's prime time schedule to just six days, as opposed to seven on competing networks . 1970 also saw the premieres of several soap operas including the long - running All My Children, which ran on the network for 41 years . </P> <P> In 1970, the FCC voted to pass the Financial Interest and Syndication Rules, a set of regulations aimed at preventing the major networks from monopolizing the broadcast landscape by barring them from owning any of the prime time programming that they broadcast . In 1972, the new rules resulted in the company's decision to split ABC Films into two separate companies: the existing Worldvision Enterprises, which would produce and distribute programming for U.S. syndication, and ABC Circle Films as a production unit . Worldvision was sold to a consortium of ABC executives for nearly $10 million . </P> <P> In April 1970, Congress passed the Public Health Cigarette Smoking Act which banned cigarette advertising from all television and radio networks, including ABC, when it took effect on January 2, 1971 . Citing limited profitability of its cinemas, ABC Great States, the Central West division of ABC Theatres, was sold to Henry Plitt in 1974 . On January 17, 1972, Elton Rule was named President and Chief Operating Officer of ABC a few months after Goldenson reduced his role in the company after suffering a heart attack . </P> <P> In the early 1970s, Michael Eisner, who joined ABC in 1966, became the network's program development manager . He helped bring about ideas for many series including Happy Days (which originated as a segment on the anthology series Love, American Style), as well as several soap operas; however, Eisner's main credit at ABC was for developing youth - oriented programming . He was responsible for reacquiring the rights to the Looney Tunes - Merrie Melodies library, bringing the shorts back to ABC after spending several years on CBS, as well as developing The Jackson 5ive animated series and a series about the Osmonds, and greenlighting Super Friends, based on DC Comics' Justice League of America series He also laid ground - work for the development of educational children's programming (predating the 1990 Congressional passage of the Children's Television Act) through interstitials such as Time for Timer, The Bod Squad and, perhaps most famously, Schoolhouse Rock! . Eisner left ABC in 1976 to become president of Paramount Pictures; he would later become the President of ABC's eventual parent company, Disney . </P>
