Vox Media has introduced a video subscription program, where it will ask its audience to pay either $4.99 or $9.99 a month for extra content exclusive to members.

The lower tier for the Vox Video Lab program, which runs on YouTube, gives members access to “video extras, including directors’ commentary, behind-the-scenes content, what-to-watch recommendations from Vox staff, access to chats and other ways to engage directly with Vox creators,” according to a post on Vox Media’s website.

The more expensive tier adds allows members to be included in the Vox Video Lab member advisory board, as well as the chance to participate in its editorial process and give feedback, according to a post from Vox executive editors Mona Lalwani and Joe Posner.

The membership program will “help us give you even more ambitious explainer videos and series,” they wrote.

Like many publishers, Vox Media is eager to experiment with new revenue streams to make up for a struggling online advertising business.

The Vox Video Lab is funded in part by the Google News Initiative, which helps newsrooms strengthen their online video capabilities and formats.

Vox Media is one of 87 recipients selected for the program.

This year, BuzzFeed News also started asking readers to make donations between $5 and $100, as well as launched a recurring membership program for $5 a month or $100 a year.
