CNBC.com will feature on-demand video reports aimed at the business community, produced from CNBC's all-digital studio in Englewood Cliffs, New Jersey.
Additional content will come from CNBC Asia in Singapore, CNBC Europe in London and bureaus in every time zone around the world.
"We have created a truly integrated news gathering operation that leverages the assets and resources of CNBC and maximises their potential for TV and Web platforms," said CNBC president Mark Hoffman.
"CNBC.com also offers the chance to stay up to date with CNBC even when they cannot watch CNBC on their television."
The site will air three to eight hours of live programming a day, covering events that have the potential to move markets.
CNBC.com will also air a live 'Market in a Minute' newscast every hour between 9:30am and 4:30pm US time.
More than 15,000 videos of business and financial leaders will be available at launch and more than 75 new videos will be posted each day.
