Disney has paid $400M to double its stake in Vice Media, less than three months before the launch of the Viceland Channel. Sources confirm to Deadline that the conglomerate is boosting its stake in Shane Smith’s youth-focused media group to about 10%, weeks after its initial $200M buy-in. The deal values the company at about $4B. Disney has not replied to Deadline’s request for comment.

Vineland, a joint venture between Vice Media and A+E Networks, launches February 24 as a 24-hour linear channel programmed and produced exclusively by Vice. Distributed in about 70 million homes, it will replace A+E’s H2. Back in March, Vice inked its most expansive content deal ever, closing a four-year pact with HBO to dramatically increase the premium channel’s current events coverage.
