I would like a clarification in the guidelines because I see a lot of variation in the data.
British Broadcasting Corporation (BBC) [gb] is a company.
BBC One [gb] is one of the BBC's channels. It is not a separate company.
When the BBC airs a program on BBC One, which company name should be added as distributor?
If the answer is that it depends on how the distributor is credited, then what if there is no such credit?
Related, the Distributors guide is clear with regard to the BBC's streaming service:
Catch up streaming services such as USA Now or BBC iPlayer would come under the main production company for the channel (i.e. USA Network [us] and BBC [gb] respectively).*
*I think the text should say British Broadcasting Corporation (BBC) [gb] instead of BBC [gb] in keeping with the company name guidelines
