The origin country should be paired with the original air dates. It is the country where the show originally aired in.
Usually the first local (origin country) network to air the series in its original language.
No rerun, simulcast or special preview on a network other than the primary network.
Be extra careful with networks. They save even if you don't click on the Save button.
Network change: when a series moves from Network A to Network B during its initial run, both networks are added (e.g. the first three seasons of The Mindy Project aired on Fox and the last three on Hulu).
International co-production: two or more networks can be added when the series is broadcast simultaneously in the original language AND a) the countries are equal producing partners or b) international networks have a producing or "in association with" credit in the original credits.
In the context of international broadcast with time difference (e.g. US/UK), simultaneously is defined as broadcast the same day.
Random earlier broadcast on a different channel, especially in a different country, are usually ignored when the television series have a clear primary network.
- e.g. when Canada airs episodes of an American series a few days ahead of the US broadcast (e.g. Chicago Med or The Real O'Neals) the Canadian network it not added as a network and the dates are not used as the first air dates
- e.g. when Germany air the episodes of an American series a few months ahead of the US broadcast (e.g. Secrets and Lies), the German network is not added as a network and the dates are not used as the first air dates
Digital platforms are allowed as networks for web series (e.g. Netflix, Hulu, YouTube Red, CBS All Access).
