Hulu is a streaming service that offers a variety of TV shows, movies, and original content for its subscribers. However, it is not uncommon for users to notice that not all episodes of a TV show are available on the platform. There are several reasons why this may be the case:

1. Licensing agreements: Hulu licenses TV shows and movies from production studios and distributors, and these agreements often specify which episodes are included. In some cases, Hulu may only have the rights to certain episodes of a show, or may not have the rights to all episodes within a season.
2. Region-specific availability: Hulu is available in the United States and Japan, and the content that is available on the platform can vary by region. This means that certain episodes of a show may be available in one region but not in another.
3. Removing content: Hulu periodically removes TV shows and movies from its platform due to expired licensing agreements or low viewership. If a show is removed from Hulu, all of its episodes will no longer be available.
4. Production delays: Some TV shows may experience delays in production, which can result in a gap between the release of different episodes. If a new episode of a show is not yet available, it will not be included on Hulu until it is released.

Overall, there are many factors that can impact the availability of TV show episodes on Hulu. Users can check the Hulu website or app for information on the availability of specific episodes.
