Dow Jones, Bloomberg, and Reuters are the 3 big ones, afaik. They are, for most people, "crazy expensive."
I had the Dow feed for a while in RealTick It was a full-time job to read all the headlines going across it. It was nice to get Fed and economic numbers so quickly, as you mention. When CNBC reads an economic number, they usually read it off the Dow news wire. Pricing for the Dow news varies by broker. It all depends on what the broker can negotiate. If feasible, if you are close with your broker and they do not offer DJ, maybe you could get them to BS DJ into a free trial. (It worked for me)
Any other news services, the cheap ones, are going to be delayed - pretty worthless, imo. The 2 squawk boxes that I have used are not reliable for news. When a number comes out, the market is rocking and the "squawker" is devoting all of his attention to keeping up with the current bid and offer.
Gee, that "free e-book" thread disappeared pretty quickly, didn't it?
