By “less important” I just meant, for example, games that are in the beginning or middle of their respective league instead of the championship game - or shows for a series that are in the middle of a season, instead of a premiere or finale.

I know every game is vitally important to someone, or that every episode of a given show is important to a dedicated enough viewer - but season/series premieres/finales and sporting league championship games are definitely set apart from the rest. Lots of people watch the Baseball World Series finale games. A lot fewer watch every game leading up to it. Lots of people will watch the series finale for a popular TV show, even if they didn’t happen to catch every episode preceding it. That sort of thing.

I’m not too concerned about the cutoff for “popular”. If the site wants to tell me about the Curling world cup, then by all means.
