How do stocks get published so quickly and how is it so incorruptible?

Question by Pajama Wars: How do stocks get published so quickly and how is it so incorruptible?
When I am reading my tv screen and I see that a particular company has “gone up” or “down”, where did that tv station or newspaper get the information so quickly to publish? Actually more specifically, how does all this information about pricing of stocks in general get reviewed and published so instantly? How does this happen and what system enables it to happen? How is it so incorruptible?

Answer by Ken C
The prices quoted on TV are just the last trade on that particular stock on the exchange (NYSE, AMEX ect.) or NASDAQ they trade on. The last trade is reported via computer from the exchange. When you see it on TV the quotes (Prices Reported) may have up to a 15 minute delay.
So they are not pricing it themselves, they are just reporting what the last trade reported was.
Did that help???
