The 50 Longest-Running TV Series (As of 2020 - Stacker)

"From the first flicker of black-and-white programming to a modern, on-demand smorgasbord of color cable channels, television has become an integral part of American life. What started as just a few networks broadcasting over the air has blossomed into a sophisticated menu of hundreds of channels broadcast via satellite and fixed cable connections. And while some television programs may come and go in the blink of an eye, others have endured for decades. Stacker compiled a list of the longest-running United States television series, ordered by the number of years each show has been on the air. The gallery includes only first-run series originating in North America and available throughout the United States via national broadcast networks, cable networks, or syndication. Series continuations—with name changes and/or changes in network—are noted, but series' revivals are treated as separate from the originals." - stacker.com
