Why Fox, News Corp. are feeling renewed

It’s big “news” for Midtown! Twenty-First Century Fox and News Corp., the separate media giants controlled by Rupert Murdoch, have locked in plans to keep and expand their headquarters on Sixth Avenue’s famed “corporate row.”

The two companies, sources said, just signed extension and expansion leases totaling more than 1.2 million square feet at 1211 Sixth Ave., home to the fa- mous Fox News Channel “zipper.” An announcement could come as early as Tuesday, the sources said.

The 44-story, 2-million-square-foot skyscraper between West 47th and 48th streets has been home to The Post since 1995. Dow Jones, also owned by News Corp., moved there in 2009.

The tower is owned by Ivanhoé Cambridge and partner Callahan Capital Properties .

In January 2016, Fox and News Corp. decided not to pursue an idea to move to the World Trade Center. Although they said they might extend their leases at 1211 Sixth Ave., nothing was final until now.

The deal for Twenty-First Century Fox totals 784,000 square feet. It includes a five-year extension of a lease that was to expire in 2020, plus 128,000 more square feet of expansion space on three high floors. The expansion is expected to take place this year, and will accommodate Fox employees who now work next door at 1185 Sixth Ave.

News Corp., meanwhile, extended its current lease on 440,000 square feet, also from 2020 to 2025.

It was understood that Fox News Channel will now invest considerable capital to create a state-of-the-art newsroom. FNC recently launched a $30 million sidewalk-fronting studio.

Terms of the new leases were not available. Reps for both media companies, landlord Callahan and the brokerages all declined to comment.
