NBCUniversal today announced that it is making a $200 million equity investment in Vox Media, which operates technology news sites The Verge and Re/code.

Vox Media brands also include the video game news and review site Polygon. Other Vox brands are SB Nation, Eater, Racked, Curbed, and Vox.com.

NBCUniversal, which is wholly owned by Comcast, said that "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 will use the cash to fuel its growth and said it will collaborate with NBC "in many areas including video programming, brand advertising, cross-promotion, and platform technology to grow existing properties and launch new franchises.”

The official announcement comes after reports last month that Comcast was in negotiations with both Vox Media and BuzzFeed. Later this week, NBCUniversal will announce a $200 million investment in BuzzFeed, Re/code reported today.

This isn't Comcast's first stake in Vox Media, which had previously taken an investment from Comcast's venture capital arm. Vox Media also has investments from Accel Partners, Khosla Ventures, and General Atlantic.

Including the new NBCUniversal investment, Vox Media has raised about $300 million for a valuation of more than $1 billion, according to Re/code.

Comcast rival Verizon has also gotten into the news business with a recent purchase of AOL, which owns the The Huffington Post, TechCrunch, Engadget, and others.
