For example Love Island vote regularly overturned after early IT glitches (7,2)
I believe the answer is:
reality tv
'for example love island vote regularly' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'overturned after early it glitches' is the wordplay.
'overturned' indicates an anagram.
'after' is a charade indicator (letters next to each other).
'glitches' becomes 'tv' (I am not sure about this - if you are sure you should believe this answer much more).
'early' next to 'it' is 'earlyit'.
'earlyit' is an anagram of 'reality'.
'reality'+'tv'='REALITY TV'
Can you help me to learn more?
(Other definitions for reality tv that I've seen before include "Television genre using members of the public" , "Broadcast" .)
