NBC Universal has made a $200m equity investment into digital publisher Vox Media, which owns online titles including Polygon, The Verge and Vox.com.

While details of the deal were scant, the strategic partnership will see the two companies collaborate on advertising, content and technology.

NBC parent Comcast already owns a 14% stake in Vox through its Comcast Ventures investment arm. NBC’s latest investment values Vox Media at around $1bn according, to a report in The New York Times.

Steve Burke, NBC Universal’s chief executive, said: “Vox Media has a great portfolio of premium digital brands that deeply engage broad audiences.

“Vox Media has strong leadership, top editorial talent and a unique technology platform. We are excited to be making this investment and building a collaborative partnership involving editorial content, advertising and technology.”

Vox owns Polygon, The Verge, Vox.com, Eater, Racked, Curbed and Re/code.

Jim Bankoff, the company’s chief executive and chairman, said: “NBC Universal is the perfect strategic partner for Vox Media as we continue to rapidly grow our audience and business.

“NBC Universal’s valuable family of properties align especially well with Vox Media’s authoritative, voice-driven brands which span sports, tech, news, fashion, food, and more.

“We are extraordinarily excited to collaborate in many areas including video programming, brand advertising, cross-promotion, and platform technology to grow existing properties and launch new franchises.”

NBC is also expected to announce a $200m investment into Buzzfeed later this week.
