Vice’s big promise that it would bring massive millennial cord-cutting audiences to TV isn’t working.

The Post has obtained Nielsen ratings for Viceland, Vice’s 24-hour cable channel on A+E Networks, and it isn’t pretty.

Viceland, which airs rebroadcasts of “It’s Always Sunny in Philadelphia” as well as original shows like “Weediquette” and “Gaycation,” logged just 106,000 viewers in the period from Sept. 25, 2017, to Feb. 4 of this year.

That means that just 0.1 percent of US households tune in to Viceland. While the ratings are meager, Vice did gain 10.4 percent over its year-ago ratings, which totaled 96,000.

Ratings in the 100,000 range put the millennial-branded channel at the viewership level of channels like the Smithsonian Channel (104,000 viewers in 2017), Aztec America (107,000) and Great American Country (100,000). (For some context, A+E Networks, which operates Viceland, netted just over 1 million viewers over the same period. That’s up 21.5 percent from its ratings in 2017).

Viceland, which launched two years ago, replaced H2, the History Channel’s companion channel that brought in about 92,000 viewers, so in that sense, Viceland is the alpha dog — even if the channel is rumored to be a money pit.

The channel is a joint venture between Vice Media and A+E Networks, whose stable of channels includes A&E, History, Lifetime and FYI. Before Viceland launched, A+E made a $250 million acquisition of a 10 percent stake in Vice Media. That stake was upped to more than 15 percent at the time of the launch.

In May 2016, months after the channel’s launch, Vice’s chief executive officer, Shane Smith, crowed at a company presentation to media and advertisers: “We started Viceland 63 days ago. It’s the fastest ‘younging down’ of a network in television history — ever, ever. We are bringing millennials back to TV.”

Hmm. Not so much.
