While some TV shows are trendy for a few seasons before fizzling out, others withstand the test of time.
Today, the average span of a typical TV series runs for 8–10 seasons. However, you may be shocked to learn that some shows from the past have run for over 50 seasons before concluding.
Many of the shows that have released new episodes over multiple decades are children's shows like "Sesame Street" and soap operas like "General Hospital."
Here are the longest-running TV shows in history and the reasons each came to an end.

The soap opera takes place in the fictional Midwestern town of Springfield and centers around the Bauer family.
The drama's departure was mainly due to low ratings.
"It was not an easy decision to make, but we talked it over with our partners at Procter & Gamble, and we agreed it was time," CBS President Nancy Tellem said in 2009, according to The New York Times.
"Guiding Light" starred Kevin Bacon, Hayden Panettiere, Brittany Snow, James Earl Jones and many more cast members.
2. "As the World Turns," 54 seasons
