There was no Memorex around when the brontosauri were bidding bye-bye, but I think we have a pretty good idea of what they sounded like as they were going extinct.  Just listen to Brian Williams this morning.  Appearing on Morning Joe, the NBC Nightly News anchor lamented the decline of "classically-trained" journalists in favor of guys with "an opinion and a modem."  

A question from Pat Buchanan about the ebbing fortunes of the old media set Williams off on a soliloquy he assured us was not self-interested.
