Depends on what you define as "important", but with 6.5 billion people on the world, there are certain to be remarkable or notable events with great regularity and frequency.

Important to whom? What people find remarkable and notable varies wildly. What may be notable to one group (say the residents of X-town may find the mayoral election notable) might not be to another (Y-town doesn't care).

Something remarkable or notable may happen every day, but it's not necessarily the case that something remarkable or notable to a specific person happens every day.

Yes, because "the news" reports equally about all events around the world... riiiiight...

News is there to advertise, plain and simple. Whether it's paid "ads" or (anti)government policy or various lobby groups. It has very little to with 'world events', and more to do with "What will get peoples' attention".
