Series company data

This guideline was added for production companies last year:

For TV Series, as a Production company may change throughout a series run - the company should be added to the individual episodes (even if the company was the same throughout).

Companies data

I think the wording should be changed so it doesn't suggest that company data should only be added to episode pages – something like "the company can be added to both the series and the individual episodes".

If a company is not added to the series level, it is not displayed on the series page, and the series is not displayed on the company's page on IMDbPro.
