In short: No. The service is an added benefit to subscribers of participating television providers in the United States. You cannot watch NBC live without a cable subscription. Contact your local TV, cable or digital TV provider online to get access to full episodes.
However, in order to watch recent episodes of our most current series, you don’t always need a TV provider account or credits. If you are looking for free shows, the latest episodes of our newest shows are always available without a login or credits on the NBC App and some of the NBCU family of apps and sites, starting the day after they air.
