Porridge maybe? Visit company stocking it (6)
I believe the answer is:
sitcom
'porridge maybe?' is the definition.
(Porridge is an example)
'visit company stocking it' is the wordplay.
'stocking it' says the answer is hidden in the clue (the answer is contained or stocked by the clue).
'SITCOM' can be found hidden inside 'visit company'.
(Other definitions for sitcom that I've seen before include "Bread, perhaps" , "'Humorous drama based on situations, in short (6)'" , "Friends perhaps" , "this could be fun" , "Fresh Meat, for example" .)
