Gloom and doom crushing popular run of programmes (10)

'programmes' is the definition.
I know nothing about this answer so I cannot judge whether this works.

'gloom and doom crushing popular run' is the wordplay.
'gloom and doom' becomes 'mi' (I can't explain this - if you can you should give a lot more credence to this answer).
'crushing' is an insertion indicator (inserted letters are crushed by others).
'popular' becomes 'in' ('in' can mean trendy).
'run' becomes 'series' (both can mean a sequence of things).
'mi' enclosing 'in' is 'mini'.
'mini'+'series'='MINISERIES'

'of' is the link.

Can you help me to learn more?
