What are the 25 longest American series in history?

the 25 longest American series in history

This weekend, The Simpsons, already the longest-running prime-time series in American television history (and which has been renewed for two more seasons), arrives at its 700th episode! One wonders what other series are following it.

In the Top 25 longest scripted prime-time series coming to us from American channels, we find many shows dating from the beginnings of the industry. Some may never leave the standings at this stage because they have lasted. This is particularly the case with dramatic anthologies, those which fueled the mythical "first golden age". It must be said that at the time, the seasons were not 22-24 episodes, she could edit up to 42 episodes and more for example.

That said, with the recent addition of Supernatural, and certainly soon to be South Park, some have either dropped from this rankings or will soon be gone. So here are the updated rankings taking into account the number of episodes aired so far this week - we will update it shortly, of course.
