AVID:Requests for Comment/Clearer guidelines for merging pages

Sometimes, I don't understand how some companies are merged together into a single article whereas others are split from one another. This includes the Columbia TriStar Television being split off from the Sony Pictures Television page (understandably due to their large size), whereas pages such as ITV Studios have two long sections merged together. What makes the former alright to split but not the latter? Likewise, vanity card articles such as the Wayans Bros. Companies and GK Productions are merged just because they are from the same person/people, when they are likely not directly related to one another, especially when two of those cards are used concurrently.

Something about that feels off and inconsistent. Should there be a clear guideline on how merging those type of pages work? This is particularly focusing on their page size and relation with another company. Camenati (talk) 22:33, 9 November 2022 (UTC)
