Google Search started live streaming updates for stock quotes, announced the Google blog.
"Now, when you search for a ticker symbol on google.com, you will immediately see financial information right on the results page, but you used to have to refresh the page to get updated stock quotes.
Now, you no longer have to refresh the entire page to see the latest price; instead you will see live streaming updates of that stock quote.
For some markets, including the NASDAQ and NYSE, these quotes represent the latest real-time market data (be sure to read our disclaimer about real-time data)."
