With many shows on Hulu, we are able to offer the 5 most recently-aired episodes. The variation in show availability on Hulu is due to the different types of contracts that we have in place with our content providers. In this instance, the owners of a certain show have opted to allow their current-season episodes available on a "rolling basis." This means that Hulu will have a certain number of current-season episodes at a time. Once 5 episodes are posted, we will remove the oldest episode each time we add a newer one. This can sometimes include re-runs, which may mean the episodes aren't always in order.
Add these shows to your Watchlist to keep track of new episodes that have been added and which ones are expiring soon.
