In the analogy, we are trying to find a term that corresponds to “Oldest” similar to how “Popular” corresponds to “Latest.”

“Latest” refers to the most recent items. A common platform that uses terms like “latest” and “popular” is social media or streaming services where sorting options allow users to either view the most recent content (latest) or the content that is trending or widely viewed by others (popular).

The opposite of “popular” would be something that is not widely seen or engaged with, which is typically referred to as “unpopular,” “uncommon,” or “least viewed.” However, if we are sticking to terms commonly used in user interface sorting options, a more suitable term is “Archived” or “Less Popular,” depending on the context of usage. “Archived” can refer to content that is retained for the record but not actively presented or engaged with, just as “Oldest” can suggest content that exists from an earlier point in time.

So, the analogy might be concluded with “Archived” in platforms where old content becomes less visible over time while still being accessible. Otherwise, “Unpopular” could be used in environments where engagement level determines visibility alongside chronological ordering.
