NowThis News, the Ken Lerer-backed startup that is experimenting with video news, including forays into Instagram and Vine, has raised money from Comcast’s NBCUniversal News Group. The two companies tell the New York Times that NBC now owns roughly 10 percent of the company, which had previously raised $10 million. The deal is part of a larger round that will bring back previous investors including Lerer Ventures, Oak Investment and SoftBank Capital. Lerer is also putting his own money into the company in this round. NBCUniversal is an investor in Revere Digital, which owns this website.
