Specifically, Comcast says that Peacock has received nearly 22 million sign-ups since it launched in July, and that it's "exceeding our expectations on all engagement metrics in only a few months." What's not clear, however, is how many of those sign-ups come from paying subscribers.
NBCUniversal has emphasized the free, ad-supported tier while pitching the service. That tier includes a large library of classic shows and movies like "30 Rock," "Parks and Recreation" and "Saturday Night Live." However, if you want access to a larger library of content (particularly Peacock Originals), as well as earlier access to new NBC shows, you'll need to pay $4.99 per month for Peacock Premium, or $9.99 per month to remove the ads.
It's also worth noting that the service has had some major limitations on connected TVs. Peacock only launched on Roku last month and, thanks to continuing business disagreements, it's still not available on Amazon's Fire TV.
