Frequently Asked Question
In the event that two or more networks are associated with the production of the same series — i.e. Chernobyl (HBO & Sky 1); His Dark Materials (HBO & BBC One) — the rule will be that we will list the network with the first air date to be the network of record, or Original Network. So, in the His Dark Materials example, the UK (BBC One) has a premiere date of Nov. 3, and the US (HBO) has an air date of Nov. 4. So, BBC One would be the Original Network.
Beyond the initial season, the Original Network will be used for the air-dates of any subsequent season, regardless of which production partner airs those seasons first.
