@terpfear Thankyou for your PR, but Campaign Medium is the most widely used and generic term, I am not sure if we will be able to merge this PR.

@AltamashShaikh The plural can indeed be mediums or media depending on the context. Might be good to maybe ask Gillian for advice.

@sgiehl After checking with Gillian, she is also of opinion of not changing it to Media.

"I understand that media can be plural for medium based on context, but changing to Campaign Media here does not fit and could mean something else entirely - if there was going to be a change, I would rather just change Mediums to Medium. or keep all of these labels singular"
