Ad tech company AppNexus has closed a $31m (£24m) strategic investment round, including $10m funding from News Corp, owner of The Sun, Times and New York Post.

As part of the deal, AppNexus’ full suite of technology products are being made available to all businesses within News Corp, including Dow Jones and News UK.

It also builds on AppNexus’ relationship with Unruly, the video advertising technology company acquired by News Corp last September. AppNexus’ video buying platform is already tied into the UnrulyX video SSP, and the two companies say they will look to grow the market for vertical video formats going  forward.

“As we grow digitally and globally, News Corp continues to form strategic partnerships with leading technology companies like AppNexus,” said David Brinker, SVP, head of business & corporate development at News Corp. “As individual businesses in our company started adopting AppNexus products into their technology stack, we gained further appreciation for their services. We are pleased to invest in AppNexus as we continue our partnership across our news, real estate and technology assets.”
