A widely known basketball team wins NBA finals
Clickbait?
Does the average reader of science.org know what trichloroethylene is without a prompt?
> Depends on the audience i guess, im not sure i can name a basketball team.
It's bordering on tautology. After all, who else would win National Basketball Association finals - a soccer team? A more astute reader will also observe that NBA finals aren't something casually won by random teams nobody heard of - by the time they get to the finals, the team is already widely-known.
Equally informative, but non-clickbait version of the headline, would be "NBA finals complete" - or, for basketball fans, "Today is 18th of June, 2023".
More people know the names of basketball teams than know the significance of TCE.
"I work for a major search engine (rhymes with Scroogle) and...blah"
Just come out and say it at that point.
A major one.
