Only one of the top 20 TV series of all time is still going today

Only one of the 20 top rated TV shows is still running today, and it's probably not what you were expecting it to be.

Some phenomenal shows have been brought to our screens over the last few years, from brand new TV like The Bear, Severance and White Lotus, to longer-running shows like Stranger Things and Succession.

According to IMDb, though, none of them make it into the top 20 - old-school early 2000s series and even a few nature documentaries are more likely to pass them out.

But one single series that's still actually running has managed to make the cut.

In first and second place with a shared IMDb rating of 9.5/10 are David Attenborough's six-part wildlife documentary series Planet Earth II, and Vince Gilligan's unforgettable Breaking Bad.

Coming in joint third and fourth place with a score of 9.4/10 are David Attenborough's original Planet Earth series - which was released ten years earlier than part two - and Emmy-winning WWII series Band of Brothers.

In fifth, and sixth place are Chernobyl and The Wire, both with a respectable score of 9.3/10.

The next six shows all share a ranking of 9.2/10, and two of them are nature docu-series. The first is David Attenborough's marine life doc Blue Planet II, and the second is the Netflix nature series - only part narrated by David Attenborough this time - Our Planet.

Another two are space documentaries Cosmos (1980) and its decades-later remake Cosmos (2014).

The people love documentaries!

Also scoring 9.2 out of ten are animated series Avatar: The Last Airbender, beloved crime drama series The Sopranos.

That brings us to 13th, 14th, 15th, and 16th place on the chart, which all have a score of 9.1/10.

Taking those spots are award-winning fantasy drama Game of Thrones, anime series Fullmetal Alchemist: Brotherhood, WWII documentary series The World At War, and Ricky & Morty.

And finally, we have reached the only TV series on the list that is still running.

Rick & Morty has been running since 2013, and season seven is slated for later this year.

Created by Dan Harmon, and starring Justin Roiland as both Rick Sanchez and Morty Smith, Rick & Morty has won two Primetime Emmy Awards for Outstanding Animated Program, and has broken records as the most-watched show in Adult Swim history.

The final four TV series' in the top 20 - none of which are still running - all score a 9/10.

They're as follows: Michael Jordans' mini series The Last Dance, Benedict Cumberbatch and Martin Freeman's BBC drama Sherlock, old-school sci-fi horror series The Twilight Zone, and, just for good measure, Life - you guessed it - another David Attenborough mini series.
