While you can watch every episode of many NBC TV shows in the streaming library, some series may only offer episodes from the most recent season. This may be because the streaming rights for past seasons were not available. In some cases, a studio or other rights holder may license past seasons to other streaming video services like Netflix, Hulu or Amazon.
If past seasons of a series are available in the NBC library, viewing some full episodes may require a TV provider login or credits.
To see how many episodes of a show are available at a given time, go to the show details page on NBC.com or the NBC App.
