Here's why:
* Collective nouns refer to a group of people, animals, or things considered as a single unit. Examples include "team", "flock", or "jury".
* "News" is an uncountable noun. It represents a general concept of information about current events, not a specific collection of individual items.
While you might say "There's some good news" or "I heard the news about the election," these phrases don't treat "news" as a collection of individual items. Instead, they refer to the information itself as a whole.
