True comedians performing in factual TV programmes (13)

I believe the answer is:

documentaries

'factual tv programmes' is the definition.
(type of factual TV show)

'true comedians performing' is the wordplay.
'performing' indicates an anagram.
'true'+'comedians'='truecomedians'
'truecomedians' with letters rearranged gives 'DOCUMENTARIES'.

'in' is the link.

(Another definition for documentaries that I've seen is " Factual programmes".)

I've seen this clue in The Guardian.
