Advert about current airhead doing internet programmes (9)

Ross

I believe the answer is:

podcaster

I'm a little stuck... Click here to teach me more about this clue!

'doing internet programmes' is the definition.
I can't tell whether this definition defines the answer.

'advert about current airhead' is the wordplay.
'advert' becomes 'poster' (type of advertisement).
'about' means one lot of letters goes inside another.
'current' becomes 'dc' (abbreviation for direct current).
'airhead' becomes 'a' (head letter of 'air').
'dc'+'a'='dca'
'poster' enclosing 'dca' is 'PODCASTER'.

Can you help me to learn more?
