The general term for "reported by the media" (other than reported, and its non-media-specific synonyms, of course) is "broadcast".
From the American Heritage Dictionary (AHD) entry
To communicate or transmit (a signal, a message, or content, such as audio or video programming) to numerous recipients simultaneously over a communication network: a radio station that broadcasts news; an agency broadcasting an appeal for donations over the Internet.
To make known over a wide area: reporters who broadcast unchecked rumors in order to get the story out first; "The birds sang in flight because that was the only way, in this treeless terrain, to broadcast their claims across their chosen pieces of land" (Kenn Kaufman).

In media jargon, there is also the phrase "put on the wire".
Bonus fact of the day: when I looked this word up in order to have a dictionary to reference in this answer, I learned that broadcast came from the practice of sowing a field by casting seeds out over a broad area (as opposed to carefully dropping them in a line along a furrough, I suppose).
