I've noticed this on KPCC in Orange County, CA - sound bytes from a mayor's speech that's being covered, or a quick interview with someone at HBGary after the whole Annonymous attack. On one level these sound bytes are superfluous, they don't add anything beyond what the reporter is already telling us. But in addition to adding new voices to the newscast, it also assures the listener that the reporter was at the mayor's speech, has talked to people affected at HBGary, that we're not just getting regurgitated news stories as are so common (as pointed out by this article). Even the news story about Guitar Hero being cancelled had sound clips from "music experts" about the effect the game had on popular culture (essentially, his kid likes classic rock and roll now when he never liked it before) - that had limited news value, but real exclusive added value for the radio station. So KPCC is one example of a news organization doing things above board.
