Ongoing TV show (6)
I believe the answer is:
series
'ongoing tv show' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for series that I've seen before include "Set of episodes" , "Number of similar things arranged in order" , "Number of similar things occurring in order" , "Sets in sequence" , "Similar things happening one after another" .)
