YouTube on Thursday officially introduced its new subscription channel option and subscriptions start at 99 cents per month, though some cost $2.99 per month.

"Today, there are more than 1 million channels generating revenue on YouTube, and one of the most frequent requests we hear from these creators behind them is for more flexibility in monetizing and distributing content. We've been working on that and wanted to fill you in on what to expect," the company said in a blog post.

YouTube said this is just the beginning of its subscription offering—30 channels are available right now—and only a small number of select partners are in the program. Before you sign up, however, you can check out a 14-day trial from any partner. In addition, there are discounts if you buy a full year in advance. The full list of partners, according to Deadline, includes:

Rap Battle Network, Baby First Plus, BIGSTAR Movies, Big Think, DHX Junior TV,, I Love Docs Channel, Gravitas Movies, HD Net, National Geographic Kids, Nelvana's Treehouse Direct, (Roger) Corman's Drive-In, DocuRama, NuestroPix, Gay Direct, PrimeZone Sports, Acorn TV, Laugh Factory VIP, PGA Digital Golf Academy, and UFC Select.

Content can be streamed on a computer, TV or mobile device.
