The requirements for non-curated web channel shows (Youtube, Vimeo, etc) were changed. Read the new policy at http://www.tvmaze.com/faq/13/shows, under "Web Channel Shows".
The Show Extras section has been updated with information on Genres, including how we define each here at TVMaze.
The change regarding Web Channel country & scheduling is now live.
New web channel policy: The country property indicates in which country the channel operates. It should only be set for Web Channels that are available exclusively in a single country, such as CBS All Access or BBC iPlayer. If it's possible to access the Web Channel from more than one country, for example Netflix or Youtube, the country property must be left empty.
New episode policy: Episodes that premiere on a Web Channel can have their airtime set when the Web Channel only operates in a single country. For Web Channels that operate in multiple countries (such as Netflix), the airtime cannot be stored.
Because of this, episodes from "local" web channels can now be shown in the schedule: https://www.tvmaze.com/schedule?country=US&sort=1&stamp=1509321600 :)
Added to the episode policy: It's not allowed for two seasons to run simultaneously. For example, there cannot be an episode in season 2 with an airdate that's before the last aired episode in season 1. If a source provides season numbering like this, it should be discarded and you should look at the next best source instead. If none of them offer a valid season numbering, fall back to year-based numbering.
This concerns, for example, http://www.tvmaze.com/shows/4987/house-hunters.
Added show main image policy. Explaining which formats are accepted and which are not.
Added show image general guidelines. These concern the newly introduced image types such as typography, banner and background.
Added episode and character guidelines. These explain expectations on uploaded episode and character screencaps.
Added in the people policy:
Additionally, if a person's birth name/real name differs from their commonly credited name, it may be added as AKA.
The episode policy on specials was significantly (pun intended) updated.
A pretty big change in the policy for straight-to-DVD shows: https://www.tvmaze.com/faq/13/shows. They can now be added to TVmaze, provided they meet the same requirements that we have for non-curated web channels. For these shows, the new property "Dvd Country" should be used to indicate in which country the DVD was initially released.
Back in June, the policy for People was amended to allow for the "other" option for genders.
Last week, we introduced Episode Notes: various common facts about episodes that you can note down. The policy for them can be found at https://www.tvmaze.com/faq/16/episode-extras.
And just now, the policy for Characters was updated to explain how to deal with the naming of characters in comic-book based shows where double (secret) identities are common.
A new category for Episode Notes was added: Late Episode Changes. See https://www.tvmaze.com/faq/16/episode-extras for the description.
Rewrote the policy on airtime & runtime to clarify how to deal with shows that don't air in a straight-forward block of 30 or 60 minutes. See https://www.tvmaze.com/faq/15/episodes#airtime-release-time, https://www.tvmaze.com/faq/15/episodes#scheduled-runtime-episode-length. Also https://www.tvmaze.com/faq/13/shows#default-airtime and https://www.tvmaze.com/faq/13/shows#default-runtime.
Amended the policy about show main images: https://www.tvmaze.com/faq/14/show-extras#poster-main-image
Added a separate policy to clarify common confusing situations you might run into when dealing with animated shows: https://www.tvmaze.com/faq/60/animation-policy
