The deal follows an agreement in June between the three parties which allows the media organisations to publicly display real-time, last-trade data for securities listed on the New York Stock Exchange, NYSE Alternext US and Nasdaq on their websites.
In a statement, NYSE Euronext said the latest addition would broaden the availability of stock prices beyond regulator trading hours for investors around the world.
NYSE Euronext executive vice-president of data solutions, Ronald Jordan, said: "With the addition of NYSE Arca last-trade data, CNBC and Google further demonstrate their commitment to investors by making available a comprehensive array of free online real-time stock prices during the full trading day."
In other news, the New York Stock Exchange's oversight NYSE Regulation has moved to suspend and delist shares in Woodbridge Holdings Corporation ahead of the start of trading on November 20th.
The regulator made the decision after the company's market capitalization fell below the NYSE's continued listing requirements.
