Humorists offering tricks involving broadcast outlets? (9)

'humorists' is the definition.
The answer and definition can be both people as well as being plural nouns.
Perhaps they are linked in a way I don't understand?

'tricks involving broadcast outlets?' is the wordplay.
'tricks' becomes 'cons' (trick can mean to scam or con).
'involving' is an insertion indicator.
'broadcast outlets?' becomes 'media' (I can't justify this - if you can you should believe this answer much more).
'cons' placed around 'media' is 'COMEDIANS'.

'offering' acts as a link.

Can you help me to learn more?
