'college broadcast' is the definition.
'propagated' can be an answer for 'broadcast' (thesaurus). I'm not certain of the 'college' bit.

'for a year restricted' is the wordplay.
'for' becomes 'pro' (as in being 'pro' something).
'a year' becomes 'pa' (per annum).
'restricted' becomes 'gated' (gating is a kind of restricting).
'pro'+'pa'+'gated'='PROPAGATED'

'to' is the link.
