Broadcast television, for decades an oligarchy of three networks, was once the locus for most of the nation’s shared cultural moments — almost 83 percent of households in the United States watched Elvis Presley’s appearance on “The Ed Sullivan Show” in September 1956, which is said to be the largest audience when measured by that metric. In terms of number of viewers, the final episode of “M*A*S*H,” in 1983, set the record with about 106 million viewers.
The networks have also had deep ties to local communities through affiliate and owned-and-operated stations. Along the way, they minted money.
“It was a license to steal,” said Fred Silverman, the former president and chief executive of NBC who as a programmer was behind the hit shows “The Waltons” and “All in the Family.”
