The 20th century news and stock ticker used to be one of the most archetypal images of newsrooms all around the world. It was timely and exciting, if a bit impersonal, for editors to watch the wires for breaking news from the big news syndicates and select stories to run in the local paper. That ticker doesn't print everything out any more, though, and a constant stream of news is something that millions of consumers now see for themselves inside their RSS feed readers.
